If you get put on a PIP, you know what game you're playing, and you absolutely should not quit. Make them fire you, and collect unemployment. Then move on to the next host.

What game is that? It's common for employers to use PIPs to create a paper trail prior to terminating somebody who doesn't get the memo that they are not making the grade. That's because performance reviews tend to under-document problems, which leaves the employer open to problems if the matter ends up in court. (Which is not particularly surprising--most people including managers are uncomfortable giving unvarnished feedback.)
