According to Article 24 of the Labor Dispute Mediation and Arbitration Law, namely: "The parties may entrust agents to participate in arbitration activities. When entrusting others to participate in arbitration activities, a power of attorney signed or sealed by the client shall be submitted to the labor dispute arbitration commission, and the power of attorney shall specify the entrusted matters and authority. " It can be seen that the law only stipulates that the signature on the power of attorney must be written by myself, and there is no mandatory requirement for other contents to be printed or handwritten. Therefore, it is acceptable for you to write a power of attorney for labor arbitration, which is in line with the law.
