EU Directive on temporary work agencies (2008/104/EC) is to be implemented in Norwegian law within 5 December 2011. The directive contains a principle of equal treatment, which means that temporary agency workers should have equal employment conditions to those that would have applied if they had been directly employed by the hiring company. Furthermore, the directive lays down that restrictions on temporary agency work can only be justified on grounds of general interest, which may have implications for today's regulation of temporary agency work. This paper takes a closer look at the directive and what consequences it may have on Norwegian law.
