If the service period is stipulated in the training agreement, the employer shall provide special training fees and provide professional and technical training for the workers. Training can be full-time or part-time. After the employee receives paid on-the-job training from the employer, the employer may agree with the employee on the service period after receiving professional and technical training. Workers who violate the service period shall pay liquidated damages to the employer.

Legal objectivity:

Article 22 of the Labor Contract Law: Where an employer provides special training fees for laborers and provides them with professional and technical training, it may conclude an agreement with the laborers 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 the employer and the employee agree on the service period, it will not affect the employee's improvement of labor remuneration in accordance with the normal wage adjustment mechanism during the service period.
