The flexible workforce is growing. Employees in temporary and flexitime jobs now tend to remain there longer and have become less likely to move on to permanent jobs. As a result, the proportion of employees remaining in the flexible workforce for long periods – more than three years – is also increasing. For most of these employees this is not a problem in socioeconomic terms: their household incomes are barely lower than those of permanent employees, and flexitime employees and their employers invest at least as much in post-initial training.

The study used Statistics Netherlands’ Social Statistics Database, which contains registered data on jobs, income from employment, social security benefits and self-employment. The information relates to all jobs in the Netherlands from 2006 to 2010, including jobs that began before 2006. It is linked to information on self-employment, other employment (e.g. freelancers without employment contracts) and benefit periods in the 2006-2010 period.
