The Working Time directive calls for an average of working 48 hours over 17 consecutive weeks. Currently anyone in the EU can opt out voluntarily but this has been applied mostly in the UK and former East European countries such as Poland.

However, this is unlikely to be passed into law as it is well known that the EU countries that strictly follow this law are also the ones least attractive for foreign investors and have high unemployment such as France and Germany.
