Abstract
Ifa finn wants to reduce its worllforce, it may dismiss some of its workers. Alternatively, it may make workers eligible for disability benefits. Upon examination these workers formally satisfy the conditions for disability enrolment. Because these conditions allow for a rather liberal interpretation of disability, these workers could have stayed on their job had they not become redundant. We use data on Dutch firms to show that at the end of the 1980s about 10 percent of the observed inflow into disability were in fact dismissals.
