I worked in bank for 2 years, last 2 week my department hire a new employee and he wage is much higher than me $4000 anually. in same department and same position he dont have any experience too need to be train. is that call discrmination... some could help me or give me some advice.. thank you very much the bank is about 200-300 employee

It's not necessarily illegal discrimination. The new employee may have more experience (that you don't know about), education, skills (that you don't know about), be better at negotiation, or it may just be the market price. Without more information, I don't see a case here.
