I believe its coming in in 2 years time, but I think it might be earlier for coach drivers and some others. The government I believe, are trying to decide whether to keep the exemption or not. That is, they are not sure if the working week should stay at what it is now (no limit) or go to the EU rule which is 48 hours per week maximum (I think). France average working week is 35 hours.
I cannot imagine how the airlines are going to cope if that comes into force. 55 hours rostered is the usual, 60 hours (or more) not unknown. And how are they going to roster the 15 miunute breaks!!!!
