I am going to have a one-to-one meeting with my manager on my yearly performance review. During the past year, some work that I have done has made a very significant contribution to the company, and my manager is well aware of that, he told me that what I have done was a very big deal in more than one private discussion with me. I am thinking of asking for a bonus increase for my work in this coming-up performance review meeting, because I am afraid that it might be too late at the bonus giving out time if the number doesn't satisfy me, however I am also afraid whether it is appropriate to ask now.
So my questions are:
Is it appropriate to ask for a bonus increase or tell the manager that I expect to get appreciation on the bonus for the work I have done?
If so, how should I ask about it or phrase to let my manager be aware what I am expecting?
