Ask HN: What to do when your company misses payroll?

Starting in May, the hardware startup I work for has been having some money problems. They've deferred payroll a couple times, including the most recent pay period.

A couple days after the last missed payroll, I indicated I would be working from home but not in a full time manner. Since then, everyone else appears to continue going into the office and working full days even though they have not been paid. Am I wrong in my actions?

The most upsetting part for me is that on payday, no one in management mentioned we would not be getting paychecks. It seemed like they figured we wouldn't mind/notice and we would just continue working.

I have updated my resume, but have not sent it out yet. They keep saying money is right around the corner and I'd like for that to be true. So I've basically been waiting that out while keeping my eyes open for opportunities (which are sparse).

Does anyone who has been through this before have any advice? Or how would you have handled it if you could go back and do it again?

EDIT: Thank you all for your insightful comments.

After hearing how often this thing doesn't turn itself around, I am going to start sending my resume out immediately. I guess I just needed a community kick in the ass to get me going!
