For the OP...file a claim and take them to the CA Wage and Hour Division. Gather up all your proof that you worked for hours you weren't paid. It's a process but, in most states, payroll is one of the- if not THE- priority debts that must be satisfied in any judgment or legal action. Their bank account being frozen by the Feds doesn't necessarily mean they're INSOLVENT, though in some situations they are or they become so rather quickly. And, yes, don't show up for work if they're not going to pay you. Start using your valuable time to find another job while your bills are either paid or they're only a tad behind. Time isn't on your side.
