I'm part of a two person team that's in charge of the data science efforts of our company. My boss and I get along fantastically, and the only reason for my leaving is to take some time off in order to study/prepare for my PhD in the fall. The problem is that he is expecting to go on paternal leave for the entirety of June.
Part of this prep involves focusing on getting my mental health as well-adjusted as possible. I've been working for almost 2 years non-stop, usually 12-15 hour days. This will likely also be the case for my PhD, so I want some time off to be selfish and focus on myself in the months leading the PhD.
The next question is, why can't I just suck it up and stay for the entirety of June and then leave once he gets back in July? My answer to this is that I don't think July/August is long enough for me to focus on my mental health/studying before the PhD. Additionally, while my boss is fantastic I'm utterly burned out from my job and every day that I spend here makes the time required to recuperate my mental health a much harder task.
Ideally I would have June/July/August to focus on these things.
If I were to leave before the paternal leave, it would mean the team essentially dies, or that he would have to work from home or forgo his privilege to paternal leave. Neither of us are easily replaced, as in the training and experience we have are incredibly unique in the market place - it would take a new team member maybe a year or so before output is at the level they were pre- my departure.
Every day I waste not discussing this with him, the larger the impact will be when I leave. I want this discussion to happen by next week, I just need some help navigating what my moral and professional obligations are.
As a side note, my boss knows I was accepted into the PhD program, and the company I work for and the university that accepted me have offered the possibility of letting me continue at my current job in a more limited capacity while doing my PhD full time. I'm very lucky to have such a supportive company, university, and boss... but this is honestly impossible for me to do. I'm very close to a breaking point, and my depression is reaching a level that is making me worried for myself. Any help would be greatly appreciated.
