Between 1981 and 1989, former FNV employee Jan Varkevisser interviewed former union officials and former cadres of the FNV, ABOP and
CNV interviewed. The project was a collaboration between the Trade Union Historical Society and the IISH and aimed to add personal experiences to trade union history.
The files contain interviews with 42 former trade union officials. They tell the story of their private and working lives. The interviews were conducted as part of a project to provide more background on union history.
