Spot on Harry , could not have said it better
I am one of those who has made report about it and even went to speak directly with the top management and I have not been deported neither had my visa revoked as suggested by some people.
The point is that you have to do it properly , based on fact and not feelings and stay professional when you do it.
The biggest problem is this jealousy feeling all the time between the so called privileged and the others , the A , B , C , D pay scales , the British against the American or against the Brazilian etc...
Those are just pretexts for some to show their frustration of their inability to act as adult to sort out their problems.
