Last week, I came into my boss's office and found him playing a game (NES Play Action Football) on his computer. I made a casual joke about it, since this is the 3rd time I had seen him play it.
He then admitted that he had a problem with addiction and played it 6 hours a day at the office. He begged me not to tell his boss. I assured that I didn't care, and that I wouldn't tell him.
Today, my boss brought me into his office and told me that he was giving me a $10k raise, because I am a "very good and faithful employee". I was very surprised (especially since raises are usually given out at the end of the year), but thanked him.
After I got home, I realized that this raise might have something to do with that stupid game he's playing and my agreeing to be quiet about it. I can really use the money, but I am now getting nervous that this is somehow going to look like I'm blackmailing him. I really don't care that he plays that game.
Is it appropriate to just take this raise without asking any further questions? Is this something that needs to be discussed with HR?
