Today we switched the roster for lab duties up so that every person gets rotated to a new task in order to have the lab run smoothly. Normally we switch up the lab duties every quarter. Today, however, a lab co-worker decided to email everyone saying he thinks we shouldn't rotate the roster this often now. Two co-workers emailed back saying that everyone should be rotated through the roster in order for the level of work to be fair for everyone over the course of the year. This guy decides to go ahead and start changing up lab duties for everyone else except himself, since he was previously assigned a the easiest lab duties on the list, and has announced that we'll be changing up duties less frequently now. How would you deal with an issue like this if you know your PI is too easy going? I know my PI will choose to not get involved since I don't think he likes drama or confrontation. Just let things boil over and create an unnecessary power struggle, or should I go into my PIs office tomorrow and prod him until he says he will do something?
