My senior is also the training officer of the department, so he wants more people to present to show how well he's doing his 'job'. Not only do we have to present in front of the entire department, but also in front of consultant and bosses. It's literally an unofficial board interview. Basically, we do all the hard work after hours, prepping the presentation and answering deliberately difficult questions from the bosses; then he reaped all the benefits by simply reserving a room. What do I do? Malicious compliance? Call in sick/Resign on the day of presentation?
Some background info: I've already finished my degree a few years ago, so I could barely rmb what I did. The lab I work in is at public hospital; it's not a research lab or somewhere we can learn by 'sharing our knowledge'. It's already really stressful and have huge workload. This senior is notorious for only doing the minimum and giving out his work to juniors.
