My professor skipped me on Christmas bonus payment I am a fourth-year data science Ph.D. student and my professor always tends to send bonus payment at the end of November for all of his Ph.D. students.
This year, all of my teammates got the bonus, even the newly admitted students (I asked them indirectly). Some of my colleagues' behavior is so frustrating as they keep talking about the issue.
I don't know if he decided not to pay me intentionally or he just forgot me. My performance is considered excellent and he is satisfied with my publications. Should I send him an email and ask for the bonus?
Update: I got the bonus. The professor forgot to send me an email that I will get it.  I just got them in my bank account without any emails or notices... I also asked to meet my professor yesterday and today we meet and discussed my thesis table in general. He is more than satisfied with my work and performance. I did not ask or open the topic of the bonus.
I think you need a more serious conversation with your advisor. You need to know if he is unhappy with your performance and if there are things you need to do to improve it. If the answer is no, then you can bring up that you didn't get a bonus. Perhaps it was a clerical issue or an issue in the delivery. But if you are not meeting expectations it would be a time for reflection.
But asking about your performance rather than your bonus would show some sense of seriousness about your work.
