This article presents some conclusions from a research program initiated in 1995 and aimed at analysing the early exit from the workforce of workers 45 years of age and older, especially through long-term unemployment. This early exit process is envisaged as a result of complex interactions between firms' policies and practices, public policies concerning retirement, workforce training and welfare, and individual workers participating in active social networks and able to develop strategies of resistance or adaptation. Research results show how the issue of early exit from the workforce is poorly recognized by firms and State policies as well. As a result, making individuals carry the responsibility for their own employability.
