You also have needed to suffer some kind of "wrong" so that you can be compensated. If you were simply fired, they can come up with a hundred reasons for that. If you were laid off with others or not paid for your work, then you might get some compensation.

The truth of the matter is that you have to weigh your legal costs against the likelihood of getting compensation that exceeds those costs. Even in the West, that is very unlikely unless you have been mentally or physically abused in some demonstrable way and have witnesses who will testify.

In general, firing people is an employers right. You have to have proof that what they did was not within their rights. Usually, these things are pretty fuzzy and you are best to move on.

Umm, not a fact, actually, just not easy.

But the more foreigners go against the trend of just accepting the crappy treatment they get at many schools and companies, and actually start doing something about it, the easy it will become for everyone.
