How long does it take for CCB Xuzhou to cancel the contract?

The same day is fine. If both sides of Xuzhou unblocking of CCB reach an agreement through consultation, the tripartite agreement can be dissolved on the same day of negotiation. The tripartite agreement is just an ordinary contract, which is signed by graduates, employers and schools on the employment of graduates. After the graduates report to the employer and the employer formally accepts them, the tripartite agreement will automatically terminate. Tripartite agreement does not mean that graduates have signed a labor contract with the employer, and the tripartite agreement still applies to the relevant provisions of the Civil Code. If the parties want to terminate the tripartite agreement, they shall terminate the tripartite agreement according to the provisions of the Civil Code on the termination of the contract.
