Poland != all of Eastern Europe. Yes, it's the same in Romania, on paper, there are loads of rules and regulations to protect the workers, but those rules are broken all the time by employers, especially in low paying jobs, because low paid employees don't have the time and money to take those employers to court, and there are next to no unions. And the labor laws are still weaker than what workers in for example France or Netherlands would get for the same job at the same company. Then there's environmental regulations which are laughable in Romania compared to what they are in Germany. To open a dirty tire factory or a mine in Germany you'd get protests up your ass meaning you'd never start building, while in Romania everything gets rubberstamped quickly if you grease the right wheels, meaning the cost of doing business is much lower regardless of wages, as the environmental costs also factor in the total cost of doing business somewhere, not just wages.
