I'm from Hungary, and I never heard of anyone suing their employer after getting fired. I'm not saying it doesn't happen, but you have to realize that the US is super-litiguous, E.European countries in comparison are at the other end of the spectrum: it doesn't really occur to people here to sue after losing their jobs. It's just not part of the culture. Also, private individuals can't afford lawyers, and don't want to deal with them.
In much of the world people will complain to a government department if they are discriminated against, and expect the department to investigate impartially.
It is typically only in high-value cases (ie, C-level executives, sexual harassment cases where high levels of damages are expected etc) where people usually seek private representation.
Of course they do sue. There is the whole "Munkaügyi Bíróság" (Work Court or whatever) to deal with the zillion lawsuits against companies firing people. And I'm not saying it's wrong. I'm saying, more often than not, these regulations backfire, and harm those, whom they should protect. Goverments create an environment in which employer and employee see each others as enemies, literally. They promote this view. Here I experience public anger against companies, investors, banks, especially multinational companies, but even smaller companies, who look successful. "Workers" see companies as their enemies. This is plain wrong, and bad, and nobody benefits. Only the corrupt, inefficent, incompetent goverments.
Yes, you're right. My point was that Hungary is probably still better than say the United States, which is famous for being a very litigious nation. Unfortunately, I can't find number to back up my gut feeling.
As a neighboring Croatian I'm not 100% certain about Hungary but it seems very similar, so I think you need to chat with a few lawyers about this, the case about guy getting fired for coming to work drunk and then being rehired and the employer forced to pay the salaries in between because he couldn't prove his claim isn't made up :)
