The point of my posts on this issue were to try and point out what is worth fighting against and what is not. If you think you can or should fight against your, or any, employer creating a perfectly legal entity in another country then you will be severely disappointed every time. It will only stop hurting when you stop banging your head against that wall.
If you base every sparring match on squaring a ledger of legal points then you run the risk of never showing up to a fight or constantly backing away and becoming completely irrelevant (AFAP).
Just because something is legal doesn't make it right. Sometimes making a noise and raising public awareness is worth a bloody nose. Though in this case it should never have been left up to an individual.
