I have a decent relationship with the boss, but he'll be pissed at the coworker for telling me she got a raise (she told me the percent and how much cash per year it equaled. That's how I figured out her pay rate. Slightly evil of me, but it was driving me nuts). She's become a good friend, so I wouldn't want to get her in trouble.
You can bet I'll ask for a raise though when my review comes up in January.
Sadly, I think the real reason why is because my company knows they can take advantage of me and they think I don't notice.
Oh well, tonight I only had to work until 9:30. It's better than midnight!!!
