I have been in the same situation before, and every time I wanted to say something about it, I got the comment to go back to where I came from...

Unfortunately 1 of the board members of the company was a prominent figure in the Labour Department. They would not help us, as he made sure whenever someone went to the labour department, the person would be stopped.

Nice information: it was a semi government company.

If I were you I'd find a new job and forget about it...
