Informal workers are increasingly forming or joining organizations to fight for their rights, enhance their bargaining power, increase their economic power and improve their livelihoods. Their membership-based organizations (MBOs) take many forms: trade unions, cooperatives, informal associations or self-help groups.
Recognizing that combining forces can amplify their visibility, voice and power, organizations are increasingly uniting into federations and networks nationally, regionally and globally.
The majority of MBOs of informal workers tend to be local, small and fragile, so are often not visible – but they exist in surprisingly large numbers. For information on over 500 of the many informal workers’ organizations around the world, see the WIEGO Organization and Representation Data Base (WORD ). WORD is regularly updated to include new entries and information.
A wide range of organizational forms exist. At a primary level there are democratic MBOs of informal workers: unions, various types of associations, self-help groups, cooperatives and networks. There are also hybrid organizations with mixed membership, NGOs that work with informal workers, and organizations that are shifting from existing within an NGO or other community-based organization to becoming independent MBOs.
Some organize as women and workers, others begin organizing as migrant communities and then as workers. Some start to organize around savings and credit, or around religious affiliation, then grow to become unions or worker associations. For more detail on membership-based organizations, see Chen et al., 2007, Membership-Based Organizations of the Poor .
The largest union of informal women workers in the world is the Self-Employed Women’s Association (SEWA), a trade union of over 1.4 million women informal workers in India. SEWA struggles to improve the rights and working conditions of workers, and has also formed over 100 cooperatives – united into a federation – to promote economic and livelihood development and self- sufficiency. SEWA cooperatives include a full-service bank, and a health insurance provider (see Fact Sheet ). For more information, see SEWA’s profile  as an Institutional Member of WIEGO.
Awareness of the need to build stronger, more visible and more powerful informal worker organizations has been growing since the 1990s. This has increased the number of national, regional and global networks, federations or alliances, some formal and some still developing and operating informally.
HomeNet International was formed in the early 1990s around the struggle for an ILO Convention on Homework. Although Homenet International did not survive, two sub-regional HomeNets were subsequently founded: HomeNet South East Asia , and HomeNet South Asia . Both these networks are currently composed of country HomeNets, which are a mix of MBOs and NGOs. They focus on policy advocacy, sharing experiences, supporting and helping to build the capacity of their affiliates.
The first international meeting on street vendors in 1995 resulted in the Bellagio Declaration , and in 2000 the StreetNet Association was set up, paving the way for the launch of StreetNet International  in 2002. StreetNet International is made up of democratic street vendor organizations or organizations with substantial street vendor membership. It encourages the formation of, and affiliation by, national associations or alliances.
The Red Latinoamericana de Recicladores (Red Lacre ), or Latin American Network of Waste pickers, is a network that brings together waste picker organizations – primarily cooperatives and cooperative federations/associations – from 15 countries. The organizations work together to improve the working conditions of waste pickers and promote dialogue and exchanges between waste pickers in different countries.
Since the First World Conference, held in Bogota in 2008, waste pickers have strengthened their global connections, especially between Latin America, India and Africa. They have formed an interim Steering Committee and developed a global programme of activities. (For more, see the Waste Picker Networks  page.)
The IDWN was initiated at the first international conference of domestic workers and supporters in 2006. It was formed in 2008 with its organizational base in the IUF and supported by WIEGO. It is led by an all-women Steering Committee composed of representatives from domestic workers’ organizations in Latin America, Asia, Africa, North America and Caribbean, and more recently from Europe. For more, see the International Domestic Workers’ Network .
There is a diverse range of organizations and networks that are organizing informal workers with differing strategies, within and outside of the formal trade union movement. The following are examples with links to more information:
