I work as a summer job in a hotel in Guangzhou, but the salary is different from what I said when I applied for the job. I want to resign, but I'm not allowed. What to do?

If you are a summer job, you only need to inform the employer a few days in advance to resign now, and they don't need their approval.

Wage is your lawful income. No matter what reason you leave your job, your employer should pay you.

Now, you can negotiate your salary with your employer. If you don't give it, you can complain to the labor department according to law on the grounds of deducting wages and ask the employer to pay your deducted wages.
