I am a Computer Science Master's Student, currently working on my thesis at a research institute. I have multiple supervisors: A, who was my "theoretical" supervisor when I started my thesis 5 months ago, B, who is my "technical" supervisor, and C, who is my new "theoretical" supervisor, as A is leaving the company soon.
I will finish my thesis at the end of the month. My problem is the following: A would like me to publish my work as a 6-page paper in an upcoming conference, with me as the main author, and him as a co-author. The problem is, he is the General Chair of the track where he wants me to publish. He even mentioned how I shouldn't worry about the paper not getting accepted, since he has so much power there.
I expressed my worries to him about this being unfair. I've checked the website of the conference, but I did not find any policy explicitly forbidding this practice, still, I think it is not right. When I told him about my concerns, he waived them away, saying "Everybody does it like this".
Now, I am pretty sure that neither my other supervisors, nor the leader of the research group knows about A's plans, since he only discussed this with me, and didn't CC the emails about this to the other supervisors (as he usually does, because we discuss every question about my thesis together).
My question is the following: what should I do now? Should I contact the other supervisors about this? Should I just flatly deny publishing the paper in his conference? Or should I play along? As all of my supervisors will have an effect on my grade, I do not want to hurt anyone's feelings. I have less than a month left until my thesis defense, but the deadline for the conference application is in a week.
