According to labor law
Article 82 The party requesting arbitration shall submit a written application to the labor dispute arbitration committee within 60 days from the date of occurrence of the labor dispute.
It can be seen that the 60-day arbitration limitation is calculated from the date when the labor dispute occurs, not from the time when overtime pay is in arrears.
According to the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Laws in the Trial of Labor Dispute Cases (II)
Article 1 When trying a labor dispute case, the people's court shall take the following circumstances as the "date when a labor dispute occurs" as stipulated in Article 82 of the Labor Law:
(1) In the dispute over the payment of wages during the existence of labor relations, if the employer can prove that it has notified the employee in writing to refuse to pay wages, the date when the written notice is served shall be the date when the labor dispute occurs. If the employer cannot provide evidence, the day when the laborer claims his rights shall be the day when the labor dispute occurs.
(2) If there is a dispute over the dissolution or termination of labor relations, and the employer cannot prove that the employee has received a written notice of dissolution or termination of labor relations, the date when the employee claims his rights is the date when the labor dispute occurs.
(3) If the laborer can prove that the time promised by the employer is the specific date after the dissolution or termination of the labor relationship, the date promised by the employer is the date when the labor dispute occurs. If the laborer can't prove it, the date of dissolution or termination of the labor relationship is the date when the labor dispute occurs.
It can be seen that the "labor dispute day" during the existence of labor relations refers to the day when the employer notifies the employee in writing that he refuses to pay wages.
In addition, the Law on Mediation and Arbitration of Labor Disputes, which will be implemented on May 1 this year, cancels the limitation of arbitration during the existence of labor relations, and workers can claim their rights at any time.
Article 27 ..... If there is a dispute over the arrears of labor remuneration during the existence of labor relations, the employee's application for arbitration is not subject to the limitation period for arbitration stipulated in the first paragraph of this article; However, if the labor relationship is terminated, it shall be proposed within one year from the date of termination of the labor relationship.
