> I don’t see why anyone would take that deal for a few weeks income, given how much it seems to matter to the company that just laid them off.

Getting called back immediately after a layoff seems like a pretty strong indication you can get away with a lot. Also, the quality of the organization's work on your layoff should indicate the quality of work the organization should get. Just take it easy and make sure you don't give them any key knowledge they need in a decipherable way.
