I'm quitting soon and need to decide how much notice I will give. My employer hasn't done anything to encourage longer notice: contractually guaranteed severance of the number of weeks requested would be appropriate, IMO - even giving two weeks feels like a great courtesy since they can fire me at any moment without any notice whatsoever. However, past employees that have left the company have tended to give about a month's notice. I'll note that this is a small venture-backed startup and that my departure will be crippling until they can replace me (good luck in this market), but... that's not really my problem, they should have managed their bus factor earlier. Nevertheless, if I give only two weeks notice, I expect my boss to comment on the short length of the period. How should I handle that, and how much notice should I give?
My start date is more than a month out, so I have complete flexibility, I just want to take as much time as is possible as vacation in between. Being unpaid and potentially using COBRA if necessary is fine by me.
