You give two weeks. That’s the deal. Professional. Courteous.

They walk you out the same day.

You offered two weeks of transition. They decided that a person who’s leaving is a security risk, a morale problem, or both. So they take your badge, box your desk, and walk you past the people you’ve worked with for years like you just robbed the place.

Two weeks’ notice is a courtesy the employee extends and the employer revokes. The asymmetry tells you everything about who the system is built for.
