If the employing unit provides special training expenses and conducts professional technical training for the workers, it may conclude an agreement with the workers to stipulate the service period.

If the laborer violates the service period agreement, he shall pay liquidated damages to the employer in accordance with the agreement. The amount of liquidated damages shall not exceed the training expenses provided by the employer. The liquidated damages that the employer requires the laborer to pay shall not exceed the training expenses that should be shared for the unfinished part of the service period.

If there are no mistakes in the text, the agreement should be legal. However, the amount of liquidated damages agreed in the agreement should be illegal. At this time, the employer should be required to list the training expenses, and the workers should check them one by one according to the list and pay the corresponding liquidated damages without objection. If the employer still requires the laborer to pay the agreed amount of liquidated damages, it will file a labor arbitration.

In addition, the employer can deduct the liquidated damages from the wages and pay the remaining settlement money to the workers, but it is illegal to directly detain all the wages.
