Legal analysis: the labor contract can be signed on behalf of others, and the act of finding someone else to sign the labor contract on behalf of others is an entrusted act in law. As long as the principal does not exceed the entrusted authority, all the acts have corresponding legal effect on the principal. That is, as long as the laborer himself agrees, he can authorize others to sign labor contracts on his behalf.
