In such a case, 1 month compensation per 1 year worked is often recommended by labor courts (maxing out at 6 months). Again, those are not mandatory unless it goes to an arbitration tribunal or court.
I work for a pretty good company, of a decent size. I have things better than many folks in the US do with regard to my employer. I've been with them for almost 30 years. If they fire me tomorrow, I might get one extra paycheck from my employer, if I ask very nicely. There is no likely path through our legal system that will net me more than that, assuming they haven't fired me in a way that violates my civil rights.
