Here is the official list of the bank holidays for the year 2016 in France.
Bank Holidays for 2016
The 1st of May is the only statutory bank holiday. Work on this day is only allowed in some companies where the activity cannot be stopped (hospitals, public transportation, …)
Other bank holiday can exist in specific region and/or activities. This is the case in Alsace and Moselle.
Employees can work on a bank holiday other than the 1st of May. The law doesn’t indicate any salary increase for a worked bank holiday. However, collective bargaining agreement and other collective accords can state otherwise.
