You know you have a bad company when you fire people who would sneak in to do more work after they're not being paid anymore

It's not clear that he wasn't getting paid:

On the last day of the canceled project, Avitzur’s manager called him into her office to say goodbye. He hadn’t completed the length of his contract, but the company would pay it in full anyway.

“Just submit your final invoice for what’s left,” she told him. That’s when it clicked: If Avitzur didn’t submit the invoice, his contract stayed in the system. And if his contract stayed in the system, his ID badge would keep getting him in the front door.

The article doesn't specify, but I would imagine that he submitted his invoice once his badge was deactivated.

Not necessarily. After some layoffs at Atari, there was a guy who daily got past the receptionist with an old badge (not electronic) and hung out in our building's machine room. He was logged onto a Vax as some innocuous account. There was a lot of turmoil, so he got away with it for a while.

When we discovered him (I was flushing old accounts, and found this guy in our Vax room who shouldn't have been there) we ejected him, and he had the chutzpah to ask for a tape of his directories.

And this is during the non-Jobs years!

Good company, or good cult of personality.
