This paper traces the history of union involvement in training from the neo-corporatism of the 1960/70s, through the voluntarism of the 1980s/90s, to the present "post-voluntary" era, as described by Gordon Brown when Chancellor of the Exchequer. It concludes that, although that there has been significant capacity building in unions under New Labour, the lack of significant collective bargaining over training limits delivering the broad union learning agenda at the workplace.
