I think mature sysadmins accept there's a certain .. bushido to their security-critical role. It is after all their job to respond to security threats, including by revoking credentials, and to recognize that they might fall on the wrong side of that some day.

But things are different both in small companies, and non-US environments where minimum notice periods or redundancy consultations are a thing. You may put people on "gardening leave" where they're still paid but not actually working. Or it may be the case that the sysadmin is the one person who knows and controls a lot of stuff, and the employer has ended up relying on them for a smooth handover. Password and role management for the "root" of things is a real problem.
