Its illegal for the company to prevent you, but that doesn't help any employee who doesn't know this fact.
Also, that is kinda the whole point of the anti-work movement, to stop working for companies that abuse you.
>And if no such company exists, you can start one.
I think you have an imperfect view of the situation given you likely work somewhere that pays you enough you have spare money left over to save up a rainy day fund. This movement isn't for you, and you should step out of the way.
Min wage workers don't have a rainy day fund, they don't have any money left over to put into a savings account, they can't even handle missing a single day of work without one of their bills being paid late, all while working a class of jobs that rarely has paid sick time, almost never has vacation, and no union to keep you from being fired for arbitrary or made up reasons.
How da fuck do you expect them to start a company? Its hard enough for them to handle the expense of changing jobs just from the one or two extra days between paychecks because they pay out on a different day.
