If the part-time boss doesn't get paid, is it reasonable to send a text message telling him to sue him for fraud if he doesn't get paid?

Wage arrears are labor disputes and do not constitute fraud.

The two sides can negotiate to solve the problem of labor remuneration.

If negotiation fails, you can complain to the Labor Arbitration Committee or apply for labor arbitration to the Labor Arbitration Committee. If they are dissatisfied with the arbitration result, they can bring a civil lawsuit to the court.
