Changing jobs because of work-related injuries can reduce wages. If an employee is incompetent after work-related injuries, the company can adjust his post. However, if there is a dispute between the two parties, the unit should prove that the transfer and salary reduction are completely reasonable. Enterprises should formulate perfect and effective rules and regulations or assessment standards as the basis of their measurement. If the employer can't prove that the post adjustment and salary reduction are completely reasonable, the post adjustment and salary reduction are invalid, and both parties shall perform according to the original contract. Legal basis: Article 35 of the Regulations of People's Republic of China (PRC) Municipality on Work-related Injury Insurance, if an employee is identified as a first-class to fourth-class disability due to work-related disability, he/she will retain his/her labor relationship and quit his/her post, and enjoy the following benefits: (1) A one-time disability subsidy will be paid by the work-related injury insurance fund according to the disability level, with the standards as follows: 27 months for first-class disability, 25 months for second-class disability and 23 months for third-class disability. (2) Pay the disability allowance from the industrial injury insurance fund on a monthly basis. The standard is: 90% of my salary for first-degree disability, 85% for second-degree disability, 80% for third-degree disability and 75% for fourth-degree disability. If the actual amount of disability allowance is lower than the local minimum wage standard, the industrial injury insurance fund will make up the difference; (3) After the workers with work-related injuries reach retirement age and go through retirement formalities, they will stop paying disability allowance and enjoy basic old-age insurance benefits in accordance with relevant state regulations. If the basic old-age insurance benefits are lower than the disability allowance, the industrial injury insurance fund will make up the difference. If an employee is identified as one to four disabled due to work-related disability, the basic medical insurance premium shall be paid by the employer and individual employees on the basis of disability allowance.
