It sounds like this employee's boss was wildly determined to keep things as unreasonable as humanly possible. They met their employee's decision to part ways after not receiving a rightful holiday bonus, with disappointment.
Clearly, someone needed a serious wakeup call. Redditor u/Wellthatwasjusts*** writes, "I'd say nothing. I worked for a smaller business that did profit sharing, had a banner year and gave out a minimum of $500 gift cards to even new employees. I was skipped. I was told it was an accident and that someone just miscounted. I had been there three years at that point and put in some stupid hours, esp after going salary. I wasn't depending on the bonus but it was a real kick in the teeth. It made me feel less than and I started looking at leaving after that because they never made it right and I was one of three people excluded. When I put in notice to leave, my boss knew because he said. "This is about the Christmas bonus, isn't it? If it was that important to you, you should have spoken up." I did... I expressed my disappointment. He said.."I just thought you were venting. I didn't think you'd actually leave over this. I can't express to you how disappointed I am that you would leave us right now over some gift cards at Christmas. He never got the point."
