Is the transfer notice valid without signature?

Legal analysis: in the absence of special provisions in the labor contract, job adjustment, as an important part of contract change, must meet two basic preconditions:

1, both parties reached an agreement through consultation;

2. Take a written form. Both are indispensable. If the employer unilaterally transfers the post without consensus, the employee has the right to refuse. The labor contract shall continue to be performed in accordance with the original agreement.

Legal basis: People's Republic of China (PRC) Labor Contract Law.

Article 35 The employer and the employee may change the contents agreed in the labor contract through consultation. Changes to the labor contract shall be made in written form. The revised text of the labor contract shall be held by the employer and the employee respectively.

Article 3 The conclusion of a labor contract shall follow the principles of legality, fairness, equality, voluntariness, consensus through consultation, honesty and credibility. The labor contract concluded according to law is binding, and the employer and the employee shall perform the obligations stipulated in the labor contract. This means that if the contract stipulates that "the post of employees can be adjusted according to needs", it should be understood as the true meaning of both parties. The terms of the labor contract are binding and should be performed by both parties.
