At my last job, every time they added or removed someone’s key card access, the system would reboot and everyone would be locked out for like two minutes.

We also had two floors that were connected by a fire stairwell, so you needed a card to re-enter the next floor.

At least twice my card stopped working in the middle of the word day while I was standing in the stairwell and I assumed that they just fired me and assumed I’d see my own way out.

Survived three layoffs at that company.
