In this article we document and discuss homeworker ‘mapping’ as an emerging approach to organizing. Mapping was used by homeworker organizations to organize unprotected workers in the unregulated informal sector where there has been an exponential growth over the last two decades (Beneria, 2001; Beynon et al., 2002; HWW, 2002; ILO, 2002b: 13). Within this sector, homeworkers are one of the largest groups with Homenet (2001) estimating that there are 300 million homeworkers world wide. They are also among the most marginalized of workers (HomeNet, 2001).
