Greek here.
I and many thousands of people like me have already been working 6 or 7 day weeks for years now. I've worked 50 hours this past week (no paid overtime either) and I've done 70 hour weeks this year, but not regularly, so I'm actually one of the lucky ones.
The only difference this makes is legalizing it so boss can't be sued or fined.
Retaliatory tactics are all too common. Your life is made miserable within the workplace (if you don't get fired) and then good luck being hired somewhere else in the same field.
You can be fired after a year without a severance package for no reason.
Where I work now we're short staffed on pretty much every department and yet we won't offer higher wages to attract new hires, cause then you'd need to raise the wages of the tenured people as well.
Instead, you squeeze the everloving shit out of whoever stays for the same money as the last 5 years while inflation is still soaring.
