So I am considering a PhD position as it appears one opened up and I was contacted about it by a professor. I'm not desperate to get a PhD. I think it's a nice goal and I am interested in the subject but its completion is not something I am dead set on.
I have read some horror stories about hours worked which I refuse to fall into. I plan on documenting my hours worked and limit it to about 9-5, mon-fri, basically view it as a very poorly paying industry job while maintaining time for personal projects/startup ideas.
So my question is if my advisor starts to get pushy and demand I spend more time working, what's the best way to respectfully maintain my boundaries?
I figure the worst that could happen is my advisor cuts my funding at which point I would terminate. Practically speaking my MS is complete so besides giving me a bad reference there's not a ton that could be done to me.
