I saw this go down right in front of me once. She technically still worked for us for 2 weeks I believe, but I saw HR approach her, bring her out of the room for a few minutes, then she came back and started quietly packing things into a box, and left within the hour.
I don't know the full details, I think she did have some kind of warning weeks before, but ignored it because she thought she was immune to being fired. She was the worst developer I've ever worked with so far though, personality-wise and skills, she definitely lied in her PHP interview. That's also on that company though, I have no idea how she passed that interview (okay, I do have an idea, no programmers ever spoke with her).
