I've been offered and accepted a new job role. Formal offer letter /email should be with me on Monday. It's a role with the same company, but in a different location. So, manager's etc are different. Due to staffing issues I know my boss is going to really struggle without me and it's not going to be easy or quick to recruit a replacement who will be able to hit the ground running, due to the nature of the job and the training/compliance that a new starter must go through. Also, someone else in my small team handed in their notice today, which my boss has not reacted well to.
I know I am perfectly within my rights to leave and of course it happens in companies all the time, but I know I'll be leaving the team in the lurch and I do feel bad about it.
I'm dreading telling my boss and have a feeling they're going to react really badly. Due to coronavirus we're home working at the moment. I'm not sure whether to do it by email, phone or request a zoom call.
I guess I'm just after advice on the best way to go about it and how to handle it if they react badly.
