Can the company directly say that all three parties have lost money without giving a cancellation letter?

After the employer terminates the tripartite agreement, the employer does not give a letter of termination, which is a contract dispute. The parties concerned shall settle the matter through consultation. If negotiation fails, a lawsuit may be brought to the people's court.

Article 565 of the Civil Code of People's Republic of China (PRC)? If one party claims to terminate the contract according to law, it shall notify the other party. When the notice reaches the other party, the contract is terminated; If the notice states that the debtor fails to perform the debt within a certain period of time, the contract will be automatically terminated. If the debtor fails to perform the debt within the time limit, the contract will be terminated at the expiration of the time limit specified in the notice. If the other party disagrees with the termination of the contract, it may request a people's court or an arbitration institution to confirm the validity of the termination of the contract.

If one party brings a lawsuit or applies for arbitration to claim to terminate the contract without notifying the other party, and the people's court or arbitration institution confirms this claim, the contract shall be terminated when a copy of the complaint or arbitration application is served on the other party.
