Sign a written labor contract within the first month; register for social insurance within 30 days
Grade ABig benefitMoneyHigh costLittle timeNo willpower
If someone works a full month without a written contract, from the second month you owe double wages each month until the end of the first year. Social insurance must be registered within 30 days of hire; failure to register and failure to correct after the deadline draws a fine of 1–3 times the premiums due. There is no «employee voluntarily waives social insurance» in law.
- Cost
- The employer share of social insurance must be paid continuously; rates vary by locality. The contract itself costs nothing—use the local human-resources department's template.
- Benefit
- If employment reaches one month but stays under one year with no written contract, double wages are owed every month. From day one of work, social insurance registration is due within 30 days. Failure brings an order to correct first; after the deadline, a fine of 1–3 times the premiums due, plus 500–3000 yuan on the person who handled registration. Late or insufficient social-insurance payment adds late fees at 0.05% per day from the due date; still unpaid after the deadline, another fine of 1–3 times the arrears. The employer must declare and pay in full on time. Only statutory force majeure such as natural disaster allows delay or reduction. There is no «employee voluntary waiver» (nationwide).
- Notes
- Double wages run from the second month through the end of the first year—delay gets more expensive. An employee without a contract or without social insurance who is injured at work, or who arbitrates after leaving, often costs far more in back premiums, fines, and compensation than any savings. How employees claim double wages: section 19, item 20.
