I work for a manufacturing company, and I got a $500 (pre tax) bonus this year. I think last year and the previous year it was $250. We had a very good year though, better than expected.
I don't think that a company is entitled to give out bonuses. Sure, it's nice. But some companies just don't do it.
What would I do in that situation? Nothing. It's amazing that I'm still employed with the amount that I screw up
So I'd keep my yap shut.
Maybe ask your boss if you're getting bonuses? And if not, ask why. I don't know. I don't think people should expect a bonus at all.
