1. If this position cannot be separated from you in a short time and there are many things that need you to deal with, then I suggest you consider it from the perspective of the unit and try to squeeze out some time after work to complete your graduation project.
2. If your current job is easy to be imitated by other colleagues, or you are just an intern, then you should give a good feedback to your superiors, and the general unit will approve it.
So, this is a small problem. You should think it over before communicating with your superiors. Both the unit and the school can be flexible.
