Well, all these laws are applicable for privileged natives.

If you are an immigrant, even from the US or other first-world country, good luck — you’ll be given contractor arrangements and fixed-term positions, still with low compensations.

EU worklaws apply to everyone working in the countries, as long they are legal, and willing to fight for their rights.

Sure, this is why you won’t be offered a permanent position (say, in France). Too much hassle. Much easier for them to hire you as an unprotected contractor.
