In 2006 new social policy legislation was introduced in the Netherlands, under which employees with chronic health problems may be assessed simultaneously as partly sick and partly able to work. In 2009 a research was conducted with as central research question: Which factors elicit the labour market participation of these partially disabled employees? This study is part of the program Re-Integratie Verbeter Onderzoek (RVO), Re-integration Improvement Research. This study reports results from a survey in 2009 of 772 partially disabled employees in the Netherlands and includes results from depth-interviews with 43 respondents.
