I don't know enough about the laws work to comment, so I can only go from personal experience. I have seen, and experienced being shuffled around, given the worst assignments and generally had huge hints dropped about not being welcomed. Some things seem so blatant, that I can't believe people aren't escorted from the building immediately. EX: The manager who had employees in his office, playing poker, for money. A new director came in soon after that event and whenever there was a situation in the manager's area, the director shadowed him, watching his every move and working directly with him. He got the idea and left.

That same director gave me good reviews on my work, but constantly gave me trouble about my attitude. This included my lack of enthusiam for the "corporate culture" and my complaints about people sitting on the phone, listening to the radio etc. I also left, and since then the company has reduced a lot of staff and actually cut back on its volume of business. It is a subsidiary, so I can't explain why the parent company made that decision, but I can see that they had a plan to save money by getting people to quit rather than "let them go."

I don't know how the law works, but my guess is, if you say to someone, "we don't like you and/or our income is reducing, we want you to quit", they have the right to leave and collect unemployment insurance.
