Despite research documenting social economy organizations (SEOs) as important labour market intermediaries in the informal economy, the impact of these organizations on employment outcomes experienced by workers engaged in these labour markets is relatively unknown. This article analyses the impact of day labour worker centres on employment outcomes experienced in the informal day labour economy of the United States. Using data from the National Day Labour Survey, findings indicate that these organizations improve working conditions for day labourers and suggest the potential for SEOs to regulate employment processes within the informal economy. However increasing the regulatory capacity of SEOs will require addressing larger political and socioeconomic contexts in which the informal economy is embedded.
