The trick is to not have to actively do anything, but rather take advantage that employment termination means you legally can not actively do things. A case I recall from a friend was a coworker of his who simply happened to be the only one to know how a particular critical system operated, because the rest of the staff never bothered reading the documentation for emergency. He was not paid for his overtimes for long enough and when he eventually stopped taking overtimes, they fired him for some AI-grade hallucination like “lack of commitment”. Four days after he was fired, they tried to order him to come back for an emergency like he owed them that maintenamce. Though cookie, the company and he signed an employment termination agreement to both their satisfactions that he has no legal obligation to the company.

From what I recall, the recovery procedure was three lines over a telnet connection. No one could even bother to open one (1) tab with the doc and type “HyperTerminal” in the Windows menu, lol.
