Last year in June i was fired from a company for mobile phone use whilst at work (I just checked the time on the screen and put it back in my pocket)...i appealed my case but was told "company policy states that mobile phone use is not allowed under any circumstances" and was dismissed and that was that, untill i discovered last month that another employee who was dismissed for the same reason at the same time i was has been reinstated.

Having found this out i filled in a application form (which i made copies of) stating that i would also like the same opportunity of re-employment as the other guy and today i get a letter saying all positions are full which i know to be bs because they are still advertising for staff.

Is this discrimination? and if so what can i do?
