Usually I don't give anything, not even a card. I'm thinking maybe a card just to three people who are my superiors and the dept. secretary (because she's nice to me) this year. Would it be good manners to just give cards to your superiors and not the other people in your dept., like coworkers? There are a lot of people, and there are some I don't even know well. Or is it good etiquette to give everyone a card?
