I am a fairly new manager and only have 1 direct report. Our working relationship has been decent up until recently. I am 4 months pregnant with my first and i am going through a lot of changes. Some days are better than others. I let my direct report know that i was pregnant to keep him in the loop because my morning sickness is bad. He seemed genuinely excited for me. However, over the last couple of months i have been noticing his mood shifts when i have off days. Some days i feel very overstimulated and try to do work that does not require a lot if face to face interaction. If i need to interact i do, but i try to give myself a buffer. I does not happen very often but I think it is just hormonal shifts that go along with pregnancy. I swear he picks up on this and that same day starts in with all of the things that are frustrating him and need to be fixed. Now this would be fine if he simply stated said frustration and context but he keeps going on about how ridiculous this is and how he hates working here etc. It seems like he bottles up all of the stuff that is happening over a period of time and then explodes when i am feeling off. I have tried talking to him about having an open dialog and we can discuss things in the moment if they are bothering him or if he needs help so we can address the situation in a timely fashion. I also have noticed when he gets like this his tone becomes passive aggressive and it gets directed at me in ways that i do not feel are professional or encompass our working relationship. For instance, he sent me a barage of Teams messages one day over a 10 minute span and instead of allowing me time to respond kept repeating in more escalating language the same thing about how he could not do his job and that he did not feel valued etc. This all came out of left field to me as i was not aware he was having issues and he kept sending messages about the same problem. I respnded by saying i was not aware of the situation but would handle it however i needed to be given time to act and having a continuous stream of messages without time to figure out what was needed was overwhelming and stressful. His response was that he did not realize i was so sensitive and that he would do better to make sure he did not stress me out. In additon he seems to get angry when i take PTO and constantly requires assistance. I thought it had more to do with me forgetting to tell him about my schedule so i have been more cognizant of communicating my schedule early and often. It seemed to help but then this week when i took a half day for a doctor's appointment he started in with everything was on fire and he needed help with xyz. I am concerned because i will be going on maternity leave in the fall and want to make sure things do not fall apart. Has anyone else had experience with this behavior? If so how did you handle it?
