I found out while i make 25 an hour my colleagues are all making around 40-45 an hour for the same job. We are contractors with an assignment for a big financial company and i just hit my one year. Im so pissed imagining what my life could have been like the last year making even $10 more an hour. I am going to try to negotiate a raise, obviously it would look suspicious if i asked for a $15-20 raise but would a $10 raise be reasonable? I figure even if its not they could meet me in the middle without being suspicious of the ask
