Are others complaining to you about his behavior? Because you’re his boss, I wonder if this could function like any other improvement conversation.
What if, instead of calling him “annoying,” you pulled him aside separately at another time and phrased the convo as wanting him to focus on “professionalism” and/or “work appropriate behavior”? If you are clear about what that means and bring examples to the table, that might help.
You could cover his passive aggressive responses in the conversation as well–pointing and writing notes and pity-partying are not appropriate ways to communicate in your workplace.
Same. If it smells clean and looks clean, then it’s clean enough for my needs. Any mustiness though, and in the wash it goes.
I’ve found that in the summer, I’m lucky if it still smells good in two days, but in the winter it can sometimes last 4-5 days.
