Temporary employment, part-time employment, marginal employment, fixed-term employment - these so-called atypical forms of employment have been increased since the 1990s. The report "Safety and health at work 2012" shows that in Germany one in five persons are in employment arrangements of this kind. Often, one person displays several of these "atypical" characteristics, for example, he or she is employed on a marginal and a fixed-term basis. This factsheet focusses on temporary workers. Using the data from the BIBB/BAuA 2012 Employment Survey, the working conditions to which temporary workers are exposed and the state of their health is shown.
