The government will punish me and the company if I do that. I am also forced to take my vacation. Even when the government says I can't go anywhere. I. Must. Not. Work.
If you're talking about labor laws, that is not true. They only specify that the employer cannot demand you to work 7 days a week, but you still can if you choose to (e.g. as a contractor).
I'm not sure what country you're talking about but that ain't what it's like where I live.
