The arbitration tribunal shall conclude the labor dispute case within 45 days from the date when the labor dispute arbitration committee accepts the arbitration application. If the case is complicated and needs to be postponed, it may be postponed with the approval of the chairman of the labor dispute arbitration commission, and the parties concerned shall be notified in writing, but the extension period shall not exceed fifteen days. If the arbitration award is not made within the time limit, the parties may bring a lawsuit to the people's court on the labor dispute.
