No work stuff is hosted in my personal accounts, and work accounts are always created with a separate e-mail. I can just remove myself from everything work related without touching anything personal.
While I was working with a small group, we had our own domain and e-mail addresses as a perk. My relationship went sour with the lead of the project and, as a power move, she disabled my e-mail and other accounts related to that group, guessing that a lot of stuff is connected to this e-mail (since the domain was prestigious in that circles) and doing so will hurt me a lot.
Since only things related to the group/work was on that e-mail, literally nothing happened. I just broke off cleanly from the group and, a move designed to hurt me brought bliss to the parting process.
