 The vast majority of countries today mandate a minimum amount of paid annual leave by law, though the United States is a notable exception in mandating no minimum paid leave and treating it as a perk rather than a right.Most countries around the world have labour laws that mandate employers give a certain number of paid time-off days per year to workers.Canada requires at least two weeks (and at least three weeks for most workers in Saskatchewan); in the European Union the countries can set freely the minimum, but it has to be at least equivalent to 4 working weeks.
