Let's be clear. By "shutting them down", you mean legally prohibiting anyone from voluntarily agreeing to work differently than one university student (who doesn't even work there) would prefer, am I right?

What should be the penalty for those who try to do it anyway?

Because "voluntary" is only just that as long as you have many other options and can easily get away from such a place. In most industries that kind of job security/market fluidity that just isn't the case. Workplace standards are there to protect workers from being exploited. In much of Western Europe the work week is standardized to 40h/w.You can work overtime, but only within certain boundaries for shorter and longer aggregated periods to avoid every day being crunch time.
