As the guy who literaly turned off the lights at a company, I agree with the thoughts on hanging in there.
The thing to remember is that it is unlikely to be financialy rewarding.
Another place that I worked, I used the "as long as I'm being paid" rule, and started job-hunting the day a paycheck was late. As a major stockholder, that was a sad decision. But I was concerned that a quarter with lots of unpaid labor would establish a financial baseline that would be impossible to maintain while paying people. In other words, if we ever got back to paying ourselves, there would be an ugly dip in the profit graph. The rest of my team hung in there for seven years, and rumor has it they averaged less than minimum wage. Then the IRS crushed them like so many bugs, and the consequences included personal liability for company taxes.
Now I'm in a huge company where my colleagues seem to think there is security. I still practice parachute maintainance. This is a great company, but things can change in a matter of hours, no matter where you work.
