Quite apart from the question of how employment participation can be increased, there is the question of what prevents unemployed people from taking part in the employment process, and what motivations keep people with employment from working longer hours. In the report 'To work or not to work' (Wel of niet aan het werk) by the Social and Cultural Planning Office (SCP) one can read about the 'untapped working potential' of the employed, unemployed and the disabled; how willing people are to go to work and what obstacles are experienced when entering the employment market. There is also attention paid to the conditions under which people are prepared to work longer hours and people's experiences with reintegration in cases of illness, unemployment or disability.
