One of my bosses her birthday is tomorrow. One of my co-workers who plans luncheons for the bosses birthdays said we would all donate 20 bucks and we would all get pizza and cupcakes. a few of my co-workers and I decided to only put in $6. We talked about it and that was it all we did was talk. Then last week I gave her $20 thinking that everyone else was going to not knowing it would just be me and the co-worker. Today everyone told me they were only going to do $6 and plan their own thing because this coworker with the $20 the last party she planned she basically kept the money for herself. I'm incredibly angry that only me and one other 1 other co-worker gave her money. everyone is telling me to talk to her and ask for my money back but the problem is I'm worried she spent it and I don't want her to cause problems for me because she's been at the company for 7 years and she's very ghetto and assertive not to mention very demanding. Please help me I don't know what to do I only make $10 an hour that 20 bucks is a lot of money.
