Get a lawyer! (Score 3, Interesting)

Not being a lawyer, but knowing a few, plus having a few who swear by having employment lawyers, I would say that you should definitely talk to one!!

A company who chooses to terminate your employment because of research or inquiries, the results of which are not told to you, sounds quite... well illegal. Were you a regular fulltime employee? Did you sign some sort of disclaimer because you were in "security" that they coudl at any time terminate you because you could be terminated as a "security risk" ???
