My boss has figured out that I am productive, so whenever he needs something done that is even marginally related to my project, he asks me to do it. Nay, tells me. No matter how trivial, no matter if it could be done by an undergrad or a grad student (the male grad student continues to spend most of his day sitting in the office playing games on his phone. No exaggeration- he's doing it right now and has been since I came in at 10. The other grad student hasn't yet arrived.)
The problem with be productive in a selfish lab is that you never become productive for yourself. I've spent every day, all day, since Friday working on experiments for our grant due next week. Today I thought I would have some time to prepare the class lecture I'm giving on Friday for a friend's course, and my boss came in and reminded me of yet another experiment I'm supposed to do.
So do I point out that no one else has done anything today? Or suck it up and once again push off the tasks that will directly benefit me?
