1. The most effective way is to directly apply to the local labor administrative department for labor arbitration (no charge, no lawyer) and claim compensation from the unit through the award issued by labor arbitration. If you don't pay compensation, you can apply to the court for enforcement.
2. If the labor arbitration is not accepted or the arbitration is unfair, you can also bring a civil lawsuit to the court within 15 days and execute it directly through the court's judgment.
3. While claiming wages through the above channels, you can also ask the unit to pay you compensation according to the standard of 5% to 1% of the payable amount according to the provisions of Article 85 of the Labor Contract Law.
