Employer engagement with active labour market programmes (ALMPs) and related employability projects is seen as vital to their ‘success’. However, the role of employers remains under-researched – a gap which widens in relation to non-governmental programmes led by not-for-profit, third-sector organisations (TSOs). Recent studies suggest that engaging employers may depend on addressing both human resource (HR) and corporate social responsibility (CSR) ‘logics’ and linking the roles of ‘gatekeeper to jobs’ and ‘proactive strategic partner’. A key question is whether TSO-led programmes are better placed to combine these logics and roles in engaging employers to help vulnerable groups into decent sustainable employment. The article explores this through a case study of two projects in England. The findings highlight the challenges that TSOs face in having to appeal almost exclusively to a CSR logic and explores why this is the case.
