So budget meetings are happening now and prior to them, our boss said in a staff meeting that now would be the time to make requests such as more vacations, benefits, etc. A few weeks ago, I learned a newish coworker had 14 days of vacation outlined in their offer letter. This only came up because I was explaining how all hires get 10 vacation days, as outlined in the employee handbook. They showed me their letter and it indeed says 14 while mine says 10. I brought this matter up in my budget meeting, expressing that if my coworker's offer letter was indeed correct, that I would like my yearly vacation days to match. I've worked here over two years and have not requested any change in my benefits until now. My boss was shocked at this and expressed that the 14 days was an error, and that it should have been 10. The day after the meeting, my boss pulled me aside and said they “hope that I'm not making a habit of going around discussing my wages, as that prevents things like raises from being implemented.” I explained how the vacation topic came up in casual conversation with my coworker. However, I can't help but worry my chances of a raise, that has been casually hinted at before this whole debacle, are at risk. My boss is going to have to break the news to my coworker that the offer letter is wrong after nearly 6 months of working here. Should I give my coworker a warning? Should I keep my mouth shut? Should I find a new job?
