Drawing on Conservation of Resources (COR) Theory, we hypothesize that workplace ostracism will reduce work engagement and service performance and that highly neurotic individuals are more susceptible to ostracism. To test the model, we collect longitudinal data from 304 supervisor–subordinate dyads in 19 Chinese hotels. As predicated, we find that: (1) workplace ostracism is negatively related to service performance; (2) workplace ostracism negatively impacts employee service performance via work engagement; and (3) neuroticism strengthens workplace ostracism’s direct effect on work engagement and indirect effect on service performance. The implications of these findings, the strengths and limitations of the study, and directions for future research are discussed. © 2011 Elsevier Ltd. All rights reserved. 1. Introduction workplace (Wright and Hobfoll, 2004). Personal resources provide emotional resilience in the face of adversity and give individuals a sense of control over their environment (Hobfoll, 1989; Hobfoll et al., 2003) whereas job resources are the physical, psychological and social aspects of a job (Hakanen et al., 2008). Resources are motivational in nature and thus contribute to work engagement (Hakanen et al., 2008; Karatepe and Olugbade, 2009; Xanthopoulou et al., 2007). As ostracism likely depletes employees’ resources, we expect that it will negatively affect work engagement and service performance. Beyond this direct effect, we predict that neurotic individuals are more susceptible to the negative effects of workplace ostracism for two reasons. First, neuroticism has been linked to interpersonal rejection sensitivity (Mor and Inbar, 2009; Brookings et al., 2003) so neurotic individuals are more likely to perceive ostracism – either real or imagined. And second, we expect that neurotic individuals will have a greater reaction toward ostracism to influence outcomes. For example, Hitlan and Noel (2009) found that highly neurotic individuals experienced higher levels of ostracism and were less likely to constrain negative behavior. In addressing these shortcomings in the literature, we have three objectives: (1) to explore the relationship between workplace ostracism and service performance; (2) to investigate the mediating effect of work engagement on the relationship between workplace ostracism and service performance; and (3) to examine the moderating influence of neuroticism on the workplace ostracism–employee engagement relationship. The theoretical model to be tested is presented in Fig. 1. In developing and testing this model, we make two contributions to the extant literature. First, studies of ostracism typically focus on general social situations; these studies often use stu- It is important for employees in service industries to be willing and able to have friendly interaction with customers. Thus, employee engagement is a key factor in organizational productivity and service performance (Karatepe and Olugbade, 2009; Liao and Chuang, 2004; Salanova et al., 2005). One factor that may affect employee engagement is workplace ostracism. Ostracism refers to the act of being ignored or excluded. When individuals perceive ostracism, they experience stress which, in extreme cases, can contribute to cognitive and functional impairment (Williams, 1997). In the workplace, ostracism can adversely affect interpersonal behavior and harm job performance (Ferris et al., 2008; Hitlan et al., 2006). Despite the negative implications that ostracism has for performance in service organizations, its impact on work engagement and service productivity has yet to be examined in the extant literature. Furthermore, it is unknown whether neuroticism moderates the relationship between workplace ostracism and work engagement. We aim to fill these gaps in the literature by building and testing a model of workplace ostracism that draws on Conservation of Resources (COR) Theory which posits that resources are salient in enhancing well-being (Hobfoll, 1989, 1998). According to COR theory, resources are things that people value and therefore they strive to protect and sustain. Research shows that both personal resources (e.g., self-esteem) and job resources (e.g., co-worker support) facilitate employees’ effectiveness in the ∗ Corresponding author at: Hong Kong Baptist University, Department of Management, Kowloon Tong, Kowloon, Hong Kong.

Relatively fewer empirical investigations have been conducted in field-settings examining work situations. Thus, this study is an investigation of workplace ostracism, and it focuses specifically on the impact of ostracism on employee work engagement and performance. Second, little research has been conducted on individual differences (such as neuroticism) in employees’ reactions to workplace ostracism. Taken together, the study enhances our understanding of how, and to what extent, workplace ostracism affects employee outcomes. The findings have practical implications for managers in the service industry, where workplace engagement is of particular importance. 2. Theoretical background 2.1. Conservation of Resources (COR) Theory Resources are defined as “. . .those objects, personal characteristics, conditions, or energies that are valued by the individual or that serve as a means for attainment of these objects, personal characteristics, conditions or energies” (Hobfoll, 1989, p. 516). According to COR, stress will occur if there is a loss of resources, a perceived threat of loss, or a lack of resource gain following an investment of resources (Hobfoll, 1989, 1998). For these reasons, individuals attempt to conserve resources in order to deal with threatening conditions and prevent themselves from negative outcomes such as emotional exhaustion. When organizations create environments that enable employees to conserve and protect resources, they can deal more effectively with work demands, which will prevent negative outcomes (Wright and Hobfoll, 2004). Conversely, COR theory posits that resource-poor employees will attempt to protect their remaining resources by depersonalization, reducing wok engagement, and decreasing their performance efforts. Wright and Hobfoll (2004) explain that depersonalization is an attempt to minimize the resource losses that may result from interacting with clients. The COR explanation for the effects of workplace ostracism is similar to the need-threat model of ostracism developed by Williams (2001). According to Williams, continued exposure to ostracism can deplete resources necessary to motivate individuals. In order to guard against further depletion, it is likely that ostracized individuals will deploy strategies to conserve their remaining resources. But guarding against further losses may be stressful in itself because energy is expended, favors are used up, and self-esteem is at stake (Hobfoll, 1998). This makes resource-poor individuals more susceptible to further resource losses as they are less resilient and have fewer resources to guard against further losses (Wright and Hobfoll, 2004). When individuals invest resources and do not reap the anticipated benefits, stress ensues and grows (Hobfoll, 2001). Hence, COR helps explain the work of Williams and Sommer (1997), who state: “if an individual endures long-term ostracism, attempts to regain these needs may give way to despair and helplessness” (p. 694–695). 837 2.2. Workplace ostracism and service performance Drawing from research on social ostracism (e.g., Williams, 2001, 2007), Ferris et al. (2008) define workplace ostracism as the extent to which a person perceives that he or she is ignored or excluded by others in the workplace. Workplace ostracism includes actions such as refusing to interact with or avoiding eye contact with the ostracized individual. In colloquial terms, ostracism is referred to with expressions such as “giving the cold shoulder”, “the silent treatment” or “freezing out”. Ostracism, in one of its many forms, is more widespread than is commonly realized (Williams, 2001). Workplace ostracism is related to other interpersonal psychological mistreatments that reflect the “darker” side of organizational behavior, such as abusive supervision, incivility, or outright bullying. Although these activities may entail some form of exclusionary behavior, they are active forms of aggression or abuse, while workplace ostracism is a form of passive aggression aimed at the organization or its employees (Hitlan et al., 2006). In other words, workplace ostracism, compared to other forms of overt, direct, and visible undermining behaviors (e.g., verbal abuse), is often subtle or covert (e.g. silence or no response to greeting). In addition, workplace ostracism has perceptual components that vary according to the individual; what one person perceives as ostracism may not be perceived as such by someone else (Williams and Zadro, 2001). Individuals often react to workplace ostracism by attempting to fortify threatened fundamental human needs. Experimental research has shown that the reaction to ostracism can be in the form of pro-social behaviors such as higher conformity and cooperation (Williams and Sommer, 1997) or the reaction can be in the form of anti-social behaviors such as aggression or hostility (Warburton et al., 2006). Williams (2009) has further argued that pro-social behaviors reflect attempts to improve inclusionary status (need for belonging) and to regard oneself positively (need for selfesteem) whereas anti-social behaviors reflect attempts to regain personal control over the environment (need for control) or to make a contribution (need for a meaningful existence). Attempts to adapt through pro-social behaviors to re-connect may successfully reduce the likelihood of continued workplace ostracism (Williams, 2001). But if the ostracized individuals are not successful, they may perceive further rejection and avoid attempts at creating social ties; they may even begin to regard with suspicion those who are not ostracizing them. Research also reveals a positive relationship between social ostracism and unhealthy, destructive behavior, including impaired mental performance (Baumeister et al., 2002), increased aggression (Warburton et al., 2006), and a tendency to engage in unintentional self-defeating behavior (Twenge et al., 2002). As such, it stands to reason that workplace ostracism will have a negative effect on employee contributions. When ostracized individuals are excluded from conversations and social activities and perceive that they are not part of the larger group, they are likely to discount their contribution to the organization. If it continues, workplace ostracism can lead to a self-fulfilling prophecy in which the ostracized individual becomes a low-value employee. For example, Sommer and Baumeister (2002) found that when individuals with low self-esteem feel their egos are threatened, they approach their tasks with less confidence, which decreases performance. Based on the tenets of COR theory, it is predicted when individuals perceive ostracism at work, they will attempt to further conserve resources, which will result in poor service performance. Hypothesis 1. Workplace ostracism is negatively related to service performance. 838 A.S.M. Leung et al. / International Journal of Hospitality Management 30 (2011) 836–844 2.3. The mediating role of work engagement Work engagement refers to a positive, fulfilling, affectivemotivational state of work-related well-being; it is characterized by vigor, dedication, and absorption (Bakker et al., 2008). Vigor refers to high levels of energy and mental resilience, the willingness to exert high effort in one’s task, and persistence in the face of difficulties. Dedication refers to a sense of significance, enthusiasm, inspiration, pride, and challenge. Absorption refers to a state where one is highly focused on and happily engrossed in one’s work; when highly absorbed, time passes quickly and one finds it difficult to detach oneself from work. Vigor and dedication can be thought of as the opposite poles of the burnout dimensions of exhaustion and cynicism, respectively. Vigor and exhaustion span an “energy” continuum, while dedication and cynicism span an “identification” continuum (González-Roma et al., 2006). In brief, engaged employees work hard (display vigor), are involved (dedicated), and are engrossed (absorbed) in their work. There have been few studies examining the relationship between work engagement and performance, but existing results have been positive (see Bakker and Demerouti, 2008, for an overview). For example, Bakker et al. (2004) found that highly engaged employees were ranked higher by colleagues on in-role and extra-role performance. Similarly, in a survey of army personnel, Britt et al. (2005) found that soldiers who were more engaged were less affected by stress and reported less negative consequences from long hours at difficult tasks. Moreover, research suggests that job resources, such as social support from colleagues or supervisors, increases motivation and work engagement. For instance, Salanova et al. (2005) found that abundant job resources increases motivation, which improves work engagement and leads to higher levels of performance and customer loyalty. Conversely, we argue that workplace ostracism depletes victims’ resources, creating adverse psychological conditions. This notion is consistent with COR theory as mentioned earlier. When individuals lack adequate resources to meet work demands, they are then more likely to disengage from work, which will impact work outcomes. Burnout is one such stress outcome due to a chronic loss of resources without counterbalancing resource gains or replenishment (Maslach et al., 2001). Hitlan et al. (2006) found that perceived workplace ostracism decreases co-worker and supervisor satisfaction and harms psychological health. Given that workplace ostracism impacts the well-being of individuals and decreases motivation (Ferris et al., 2008), we hypothesize that work engagement acts as a mediating variable in the relationship between workplace ostracism and performance outcome: Hypothesis 2. Work engagement mediates the relationship between workplace ostracism and service performance. sible explanation for this phenomenon is that “employees high in neuroticism perceive their work environment as more threatening” (Langelaan et al., 2006, p. 529). These negative reactions are likely to increase during interpersonal conflicts (such as perceived ostracism), leading to stress and lower work engagement. As such, personality might function to constrain individual behavior (Carver, 2005) such that at low levels of neuroticism, work engagement will be similar across all levels of perceived ostracism. However, at high levels of neuroticism, work engagement varies widely according to the extent to which an individual is experiencing ostracism. For example, Hitlan and Noel (2009) found more counterproductive behavior for employees whose personality traits – including high neuroticism – exerted less self control over their behavior. As a result, the relationship between workplace ostracism and counterproductive behavior was strongest for employees whose personality exhibited less behavioral constraints. Thus, we expect an interaction effect, suggesting that the lowest levels of work engagement will emerge for highly neurotic individuals experiencing high levels of ostracism. Taken together, we expect that individuals low on neuroticism will have weaker reactions to ostracism, and ostracism will have little effect on their work engagement. In contrast, there are more pronounced changes in work engagement in highly neurotic individuals whose personality exerts less control over their behavior. Hence, building on the work of Hitlan and Noel (2009), we suggest that the negative relationship between workplace ostracism and work engagement will be more pronounced among highly neurotic individuals who are more reactive to workplace ostracism. As such, we hypothesize that highly neurotic individuals who experience high levels of workplace ostracism will have the lowest levels of work engagement. Hypothesis 3. Neuroticism moderates the negative relationship between workplace ostracism and work engagement such that the relationship is stronger when neuroticism is higher. As mentioned earlier, work engagement is likely to meditate the influence of workplace ostracism on service performance in that ostracized individuals will become disengaged from their work, which will harm service performance. Furthermore, the personality trait of neuroticism may moderate the impact of perceived ostracism on work engagement in that highly neurotic individuals tend to react more negatively to ostracism. For example, in a meta-analysis, Judge and Ilies (2002) found that neuroticism is the strongest and most consistent correlate of performance motivation. With respect to this study, this means that if highly neurotic employees perceive they are being ostracized, they will be less motivated and less engaged in their work. Hence, we further predict that the decreased work engagement resulting from the interaction between workplace ostracism and neuroticism will, in turn, undermine service performance: 2.4. The moderating role of neuroticism Neuroticism is the tendency to experience negative emotions such as fear, sadness, and anger (Costa and McCrae, 1987). Highly neurotic individuals are characterized by traits such as nervousness, moodiness, and sensitivity to negative stimuli (Nevid and Rathus, 2005). High neuroticism implies higher trait anxiety, emotional instability, and maladjustment. Individuals high in neuroticism are more prone to experience negative emotions such as anxiety and depression, and tend to be impulsive and self-conscious (Costa and McCrae, 1987; Schmitz et al., 2003), and are more likely to engage in interpersonal conflicts and find such conflicts emotionally draining (Bolger and Zuckerman, 1995). In a study of employees in quick-service restaurants, Kim et al. (2009) found that among the Big Five personality variables, neuroticism was the most highly correlated with burnout and reduced work engagement. One pos- Hypothesis 4. Work engagement mediates the interactive effect of workplace ostracism and neuroticism on service performance. 3. Methodology 3.1. Sample and procedures To test the model, we collected survey data from 19 hotels in southern China in three stages. For each of the measures, data were collected from two separate sources. In the first stage (T1 ), employees provided demographic information, their perceptions of workplace ostracism, and rated their neuroticism, while HR managers provided basic information on their firms and the service climate. In the second stage (T2 ), employees reported their degree of work engagement. In the third stage (T3 ), employees’ supervi- A.S.M. Leung et al. / International Journal of Hospitality Management 30 (2011) 836–844 sors were asked to evaluate their subordinates’ customer service performance. With data collected at three different stages from two different sources, common method variance is not an issue. Data were collected with the assistance of the firms’ HR managers, who briefed the potential participants (both employees and their supervisors) about the purpose of the study and the procedures for collecting data. Each participant received a cover letter outlining the details of the study, the voluntary nature of participation, an assurance of anonymity, as well as a questionnaire and a return envelope. The HR manager from each operation randomly selected 30–40 employees with considerable personal interaction with customers; the supervisors of these employees evaluated their subordinates’ service performance in a separate questionnaire. The employee questionnaires (T1 and T2 ) were matched to the responses of their supervisors (T3 ) using a coding system based on information provided by the HR manager for each operation. The questionnaires were conducted in Chinese but they were initially drafted in English before being translated into Chinese following the back-translation procedure recommended by Brislin (1980). We received 420 usable subordinate questionnaires and 19 usable HR manager questionnaires in the first stage of the surveys. During the second stage of the data collection, which took place three months later, we received 344 usable subordinate questionnaires. The effective response rate for the first two stages of the subordinate survey was 51.7%. In the third stage, 120 questionnaires were distributed to the subordinates’ supervisors, resulting in a usable response rate of 91.6% for supervisors. The final sample consisted of 19 HR managers and 110 supervisors, or 304 supervisor–subordinate dyads. Of the 19 hotels invited to participate, 42.1% were classified as state-owned. The average number of years of operation was 14.53 (S.D. = 5.54), and the number of employees for each hotel ranged from 87 to 323. In terms of hotel ratings, 10.5% were two-star hotels, 42.1% were three-star, 26.3% were four-star, and 21.1% were five-star. Of the 304 subordinates, 60.9% were female. The average respondent was 29.91 years old (S.D. = 5.42) and the average organizational tenure was 5.07 years (S.D. = 2.57). In terms of education, 36.8% were high school graduates, 52% held a university degree, and 11.2% had a master’s degree or above. 839 disturbed.” We conducted a confirmatory factor analysis (CFA) to test the unidimensional structure of this measure. Results indicated that the fit indexes fell within an acceptable range (2 (35) = 125.32, p < .01; RMSEA = .09; CFI = .93; TLI = .91). The reliability of this scale was .89. Work engagement: A nine-item scale developed by Schaufeli et al. (2006) was used to measure work engagement. Response options ranged from 1, “strongly disagree,” to 7, “strongly agree.” Sample items included: “At work, I feel bursting with energy (vigor),” “When I get up in the morning, I feel like going to work (dedication),” and “I am immersed in my work (absorption).” We conducted a confirmatory factor analysis (CFA) to test the threedimensional structure of this measure. The fit indexes for three first-order factors plus one second-order factor fell within a good range (2 (24) = 62.17, p < .01; RMSEA = .07; CFI = .97; TLI = .95). The subscale’s reliability was .76 for vigor, .84 for dedication, and .84 for absorption, and the aggregate reliability of the scale was .87. Following previous studies, we aggregated the 9 items to create a single index of workplace engagement (e.g., Sonnentag, 2003; Xanthopoulou et al., 2008). Service performance: A seven-item scale developed by Liao and Chuang (2004) was used to measure service performance. Response options ranged from 1, “strongly disagree,” to 5, “strongly agree.” Items included: “This employee is friendly and helpful to customers,” “This employee approaches customers quickly,” and “This employee is able to help customers when needed.” The fit indexes were good (2 (14) = 43.50, p < .01; RMSEA = .08; CFI = .96; TLI = .95). The reliability of this scale was .86. Control variables: Previous research indicates that employee demographics (i.e., age, gender, organizational tenure and education level), workplace characteristics (i.e., hotel age, size, ownership type, and star rating), and workplace service climate (i.e., perceptions of service quality) are likely to be associated with employee work engagement and service performance (e.g., Bakker and Demerouti, 2008; De Jong et al., 2005; Hyvönen et al., 2009; Liao and Chuang, 2004, 2007; Liao et al., 2009; Salanova et al., 2005; Xanthopoulou et al., 2008). Hence, we control for these factors in this research. Service climate was measured with a five-item scale developed by Schneider et al. (2000); the response options ranged from 1, “strongly disagree,” to 5, “strongly agree.” The reliability of this scale was .78. 3.2. Measures Workplace ostracism: A ten-item scale developed by Ferris et al. (2008) was used to measure workplace ostracism. Response options ranged from 1, “strongly disagree,” to 7, “strongly agree.” Sample items included: “Others ignore me at work,” “Others leave the area when I arrive,” and “My greetings have gone unanswered at work.” A confirmatory factor analysis (CFA) was conducted to test the unidimensional structure of this measure. The model’s overall Chi-square, the comparative fit index (CFI, Bentler, 1990), the Tucker–Lewis Index (TLI, Tucker and Lewis, 1973), and the root mean square error of approximation (RMSEA, Browne and Cudeck, 1993) were used to assess model fit. Convention suggests that a value over .90 for CFI and TLI and a value below .08 for RMSEA are indicative of a good fit between the proposed model and the observed data (Bagozzi and Yi, 1988). By these criteria, the fit is quite good (2 (35) = 92.02, p < .01; RMSEA = .07; CFI = .97; TLI = .96). The reliability of this scale was .92. Neuroticism: A ten-item scale developed by Goldberg (1990) was used to measure neuroticism. Response options ranged from 1, “strongly disagree,” to 7, “strongly agree.” Sample items included “I worry about things,” “My mood changes a lot,” and “I am easily 3.3. Data analysis Since 110 supervisors provided service performance ratings for 304 subordinates, there is the possibility of nesting effects (i.e., the supervisor’s rating of one subordinate may influence his/her rating of another). We tested for this potential problem by calculating the size of the design effect (Ukoumunne et al., 1999). The results (design effect = 1.53) scored below the conventional cutoff value of 2. Hence, we can conclude that the nesting effects are not likely a problem. We used hierarchical linear modeling (HLM) to analyze the cross-level data. HLM takes into account the individual-level error in estimating firm-level coefficients. It can simultaneously estimate two models: one identifies the relationships within each firm, while the other represents how these within-firm relationships vary among themselves (Bryk and Raudenbush, 1992). The relationships among workplace ostracism, neuroticism, work engagement, and service performance were modeled at the individual level; whereas hotel demographics and hotel service climate were modeled at the firm level to explain inter-firm variations in work engagement and service performance. 840 A.S.M. Leung et al. / International Journal of Hospitality Management 30 (2011) 836–844 5.5 4.1. Descriptive statistics Table 1 presents the means, standard deviations, and zero-order correlations for all of the key variables. As shown in the table, the correlations of the key variables are in the expected direction. We found that workplace ostracism was negatively correlated with work engagement (r = −.37, p < .01) and service performance (r = −.23, p < .01). Moreover, work engagement and service performance were positively correlated (r = .39, p < .01). 4.2. Tests of hypotheses Work engagement 4. Results 5.0 (r = -.15, p <.05) 4.5 (r = -.46, p <.01) 4.0 low high Workplace ostracism For employees low in neuroticism For employees high in neuroticism HLM analyses were conducted to test the first two Hypotheses. We entered the variables into the model at three steps: In step 1, we entered control variables; in step 2 we entered the main effect variable of workplace ostracism; in step 3 we entered the work engagement variable to test the mediation effect. As indicated in Table 2, we found that workplace ostracism is negatively related to service performance (ˇ = −.15. p < .05; Model 6), thus supporting Hypothesis 1. Hypothesis 2 predicted that work engagement mediates the influence of workplace ostracism on service performance. According to Baron and Kenny (1986), full mediation is supported if four conditions are met: (1) the independent variable (workplace ostracism) is significantly related to the mediator (work engagement); (2) the independent variable is significantly related to the dependent variable (service performance); (3) the mediator is significantly related to the dependent variable; and (4) when mediator is entered into the model, the relationship between the independent variable and the dependent variable becomes nonsignificant. Evidence in support of Hypothesis 2 is shown in Table 2. The results indicate that (1) workplace ostracism was negatively related to work engagement (ˇ = −.26, p < .01, Model 2); (2) workplace ostracism was negatively related to service performance (ˇ = −.15, p < .05, Model 6); (3) work engagement was positively related to service performance (ˇ = .23, p < .01, Model 7); and (4) the relationship between workplace ostracism and service performance became nonsignificant (ˇ = −.09, p > .05, Model 7) when workplace ostracism was entered. Thus, Hypothesis 2 was fully supported. To examine the moderation and the mediated moderation predicted by Hypotheses 3 and 4, respectively, we adopted the moderated causal step approach of analysis (Muller et al., 2005). Five steps were carried out: control variables were first entered, followed by the predictor (workplace ostracism) and the moderator (neuroticism) in the second and third step. The workplace ostracism–neuroticism interaction was entered in the fourth step. Finally, the mediator (work engagement) was entered in the last step while controlling for the neuroticism–work engagement interaction. All interaction variables were mean-centered to minimize multicollinearity (Aiken and West, 1991). Hypothesis 3 predicted that neuroticism moderates the relationship between workplace ostracism and work engagement. As shown in Table 2, the interaction between workplace ostracism and neuroticism was negatively related to work engagement (ˇ = −.11, p < .01, Model 4), thus supporting Hypothesis 3. We further plotted the interaction effects using Stone and Hollenbeck’s (1989) procedure; we computed slopes using one standard deviation above and below the mean of the moderating variable. Fig. 2 shows the interaction patterns, which are consistent with the hypothesis. Specifically, workplace ostracism has a stronger, negative relationship with work engagement when neuroticism is high. We further conducted a simple slope test. The results further confirmed that workplace ostracism is more negatively related to work engagement when neuroticism is high (rhigh = −.46, p < .01) rather than Fig. 2. Interactive effects of workplace ostracism and neuroticism on work engagement. low (rlow = −.15, p < .05; rhigh-low = −.31, p < .01). Thus, there is solid support for Hypothesis 3. To further test the mediated moderation, we followed the procedure of Muller et al. (2005). According to Muller and colleagues, the full mediated moderation is supported if four conditions are met: (1) the interaction between the independent variable and the moderator (in this case, workplace ostracism × neuroticism) is significantly related to the mediator (in this case, work engagement) as indicated by Hypothesis 3; (2) if after controlling for other predictors, the interaction is also significantly related to the dependent variable (in this case, service performance); (3) if after controlling for the mediator × moderator term (in this case, work engagement × neuroticism) and other predictors, the mediator is significantly related to the dependent variable; and (4) if after controlling for the mediator, the effect of the interaction between the independent variable and the moderator on the dependent variable becomes nonsignificant. We found support for Hypothesis 4; the results showed that (1) workplace ostracism × neuroticism was significantly related to work engagement as indicated above for Hypothesis 3; (2) workplace ostracism × neuroticism was significantly related to service performance (ˇ = −.06, p < .05, Model 9); (3) after controlling for the interaction between work engagement and neuroticism and other predictors, work engagement (ˇ = .22, p < .01, Model 10) was found to be positively related to service performance; and (4) the interaction effect of workplace ostracism and neuroticism on service performance became nonsignificant (ˇ = −.04, n.s., Model 10) after entering work engagement while controlling for the interaction between work engagement and neuroticism and other predictors. We further plotted the interactive effect of workplace ostracism and neuroticism on service performance and conducted a simple slope test. Fig. 3 shows the interaction patterns which were consistent with our hypothesis. Workplace ostracism was negatively related to service performance when neuroticism was high (r = −.30, p < .01) but was not related to service performance when neuroticism was low (r = −.10, n.s.). Although the procedures of Baron and Kenny (1986) and Muller et al. (2005) are widely used to test the mediation, they cannot determine whether the mediation is significantly different from zero (MacKinnon et al., 2002; Shrout and Bolger, 2002). Thus, we performed two Sobel tests to examine the significance of indirect effects (Sobel, 1982). Results substantiated that the mediating effect of work engagement is significant in the relationship between workplace ostracism and service performance (Z = 2.98, p < .01), and in the relationship between workplace ostracism × neuroticism interaction on service performance (Z = 2.29, p < .05). Therefore, Hypotheses 3 and 4 received further support. A.S.M.

Discussion In this study, we used a longitudinal research design to examine the impact of workplace ostracism on work engagement and performance. Although there is a large body of literature exploring how ostracism influences outcomes in different laboratory settings, little field research has been done on ostracism in actual work situations. One of our objectives was to address this gap by examining how workplace ostracism and one’s personality contribute to work engagement and service performance. Our model and hypotheses were based on COR theory (Hobfoll, 1989, 1998). The results sup- port the contention that workplace ostracism negatively affects service performance. The results also suggest that work engagement mediates the relationship between workplace ostracism and service performance. In addition, we found that neuroticism moderates the relationship between workplace ostracism and engagement, and work engagement mediates the interactive effect of workplace ostracism and neuroticism on service performance; in the sample, highly neurotic employees are more negatively affected by workplace ostracism. This is consistent with Hitlan and Noel’s (2009) argument that personality can function to constrain, or not constrain, Table 2 Results for hypotheses testing using HLM.

Interactive effects of workplace ostracism and neuroticism on service performance. behavior. Their findings reported that the weakest constraint on behavior emerged with individuals who are highly neurotic and experience high levels of exclusion. 5.1. Theoretical implications This study contributes to the literature in three ways. First, drawing upon COR, we develop a model to explain the consequences of workplace ostracism. The model predicts that workplace ostracism undermines resources and decreases motivation. Second, the model provides understanding of the mediating role that work engagement plays between workplace ostracism and service performance. The findings support our hypothesis that a reduction in work engagement is a reaction to workplace stress. People disengage from their work because they lack energy and motivation, which becomes depleted as they perceive they are being ostracized. Hence, the overall results offer additional evidence of the psychological strain caused by workplace ostracism. Finally, the study reinforces the idea that individual differences affect the degree of engagement and have other behavioral outcomes. As Hobfoll (2001) points out, positive personality traits can be thought of as positive personal resources, while negative personality traits can be a drain on personal resources. Thus, highly neurotic individuals are more likely to perceive they are being ostracized and are likely to feel more threatened by workplace ostracism which magnifies its negative impact. 5.2. Managerial implications Workplace ostracism has received little empirical attention in the tourism and hospitality literature, which makes our findings all the more salient. Our findings suggest that there are potentially high costs to service organizations where employees experience workplace ostracism. In view of increasing competition among service providers, our findings suggest that steps should be taken to prevent workplace ostracism or to quickly end it when it first surfaces. This is especially the case for service and hospitality firms which depend upon quality interaction with customers. There are several traditional approaches to eliminating workplace ostracism, such as holding formal and informal gatherings that facilitate interpersonal understanding and interaction. Managers can also nurture positive organizational resources to help mitigate the potentially negative impact of workplace ostracism, such as fostering a work climate with a strong service orientation (e.g., Liao and Chuang, 2004; Liao et al., 2009; Salanova et al., 2005) and a strong culture of trust to enhance the employee–customer interface (Lam and Lau, 2008). Furthermore, a preventive work environment would take corrective measures before employees become de-motivated and/or disengaged from work. Individuals who perceive ostracism are more likely to interpret other events in a threatening manner and this can escalate into a self-perpetuating cycle (Zadro et al., 2006). In this context, a proactive response system for detecting ostracism can reduce its likelihood and continuation. When workplace ostracism has been observed, managers should determine who ostracizes and why. Moreover, the targets and their immediate supervisors can work together to replenish the affected individuals’ organizational resources (e.g., professional development training) to help improve their inclusionary status or cope with ostracism. These organizational attributes can not only increase cooperation among individuals and their contributions to their work unit, but also foster interdependence among employees. In addition, managers should consider the impact of employee neuroticism, as suggested by the moderating effect that we identified. Specifically, professional training, advice, and workshops can be provided to maintain employees’ psychological well-being. When the negative effects of neuroticism are weakened, the negative influence of workplace ostracism on work engagement will be lessened or mitigated. 5.3. Strengths, limitations, and future research This study has several strengths worth noting. Data were collected from three different sources (employees, supervisors, and HR managers) which lessen problems with common method variance (Podsakoff et al., 2003). Moreover, we collected data at three distinct points in time, lending additional support to the causal nature of the model (Cook and Campbell, 1979). Nevertheless, there are also some limitations. First, ostracism may be a bigger factor in countries high in collectivism, such as China. Collectivism refers to “a set of feelings, beliefs, behavioral intentions, and behaviors related to solidarity and concern for others” (Hui, 1988, p. 17). Collectivistic cultures put heavy emphasis on close and harmonious interpersonal relationships. Therefore, employees and organizations in collectivistic cultures may be more affected by workplace ostracism (Powell et al., 2009; Wilkins and Dyer, 1988). Since our research setting was southern China, the findings may not be generalizable to more individualistic cultures. Our findings are consistent with the theoretical predictions of COR theory, which has found support in different countries over a wide range of organizational settings (e.g., Bakker and Demerouti, 2008; Hobfoll, 1989, 2001; Schaufeli and Salanova, 2007). Nonetheless, future researchers may wish to replicate this study in other settings. Second, service climate is a collective and shared phenomenon (Salanova et al., 2005). As the use of work teams increases, collective engagement at the team level may be an important source of competitive advantage (Salanova et al., 2003, 2005). Some behavioral issues at the team level may become increasingly important. For example, how do individuals attempt to regain control when they perceive ostracism in the workplace? Do they increase conformity in an attempt to bring themselves in line with the group? Or do they further isolate themselves to further conserve resources. What determines the course of action taken by a particular individual? These issues present interesting topics for future research. 6. Conclusion Drawing on COR theory, this research examines whether workplace ostracism depletes an employee’s resources, which, in turn, decreases work engagement and service performance. The results support the initial hypotheses and suggest that the negative impacts could be differentiated on the basis of personality; we find A.S.M. Leung et al. / International Journal of Hospitality Management 30 (2011) 836–844 that neuroticism strengthens workplace ostracism’s direct effect on work engagement and indirect effect on service performance. Highly neurotic individuals are more likely to perceive that they are victims of, and are likely to be more negatively impacted by, workplace ostracism. In summary, this study suggests that workplace ostracism can be harmful to organizational performance. Hopefully this study will encourage future researchers to focus attention on this negative organizational phenomenon as well as assist management and practitioners in reducing its occurrence and harmful effects.
