This study aims to examine how Algerian local associations have been
involved in networking on the part of women workers engaged in the
informal economy since the 1990s. After Algeria gained independence in
1962, the government prioritized strategic policies to exploit natural
resources; however, this policy accelerated the establishment of a
vulnerable regime that was extremely dependent on those profits. Therefore,
61
the declining global gas and oil prices at the end of the 1980s became a
crucial factor in bringing about financial instability. And the structural
adjustment program that followed further increased the number of
unemployed. The informal economy has become a popular topic for scholars
trying to understand and analyze these people’s way of life. But previous
studies on this issue in Algeria have not sufficiently focused on women’s
informal labor because most women belong to “invisible workplaces” for
example doing piecework at home. Thus, the field-work for the present
study took place within local women’s associations in urban areas, mainly in
a group settled in the Casbah of Algiers to promote training for local women.
It took one and a half months to conduct the participant observations and
interviews, which aimed to examine the association’s roles and functions in
preventing isolation of individual women, especially after the civil war
broke out in the 1990s. These associations or groups consist of local women
with close familiarity with other individuals, who were organized primarily
to promote women’s ability to produce their own profits. To conclude this
discussion of the field surveys, it is recognized that women’s groups have
significance not only in helping to commercialize products but also in giving
women a reason or excuse to get out of their homes. At the same time, these
groups help to repair the civil relationships that had been cut off because of
the disturbance to security during the 1990s.
