What do you mean by sending a message to the boss asking for a salary and he doesn't reply?

In fact, just because the boss is nice doesn't mean he won't default on his salary. And a bad boss on weekdays does not mean that he will default on his salary. The boss didn't reply to you, probably because he wanted to avoid not paying wages. If you still can't find a boss, you can apply for labor arbitration or call 12333 to complain. This phone number belongs to the Human Resources and Social Security Bureau. You can also go to the labor inspection brigade to complain about the other party's arrears of wages. If the other party is unwilling to execute the labor arbitration, it may also apply to the court for compulsory execution. These methods are all possible.
