Advice : Working for company that uses payroll as a cashflow management tool

Lots of startup people here, so I assume more than a few of you have been in this situation.<p>I am working for a startup that has been persistently skipping payroll, sometimes paying late, sometimes not at all, always with vague explanations about how the company is doing or why they missed payroll this time.<p>The company in question has a very interesting product and is primarily dealing with funding issues, so I am reluctant to cut ties completely, but it is reaching a point where nobody trusts management to deliver (lack of communication, vague when they do communicate, etc).<p>I am curious to hear from others who have been in this situation, how you dealt with it (besides simply quitting), and whether the company you worked for got its act together or eventually just tanked.
