The plaintiff claims that labor wages include the wages of others. Does the plaintiff also claim that,

Equal pay for equal work is relative, not absolute. The employing unit shall independently determine the wage distribution mode and wage level of the unit according to the production and operation characteristics and economic benefits of the unit.

Workers have individual differences, and their ability level and proficiency can't be exactly the same. It is argued that the positions and contents of employees who directly sign labor contracts with Jintai Property Company are the same as those of other employees, but their wages are different. First of all, Shi Liang was sent to Jintai Property Company by Zhitonglian Labor Service Company, and Jintai Property Company was the actual employer. The above-mentioned employees who signed labor contracts with Jintai Property Company established labor relations with Jintai Property Company, and the labor contracts were different from Shi Liang.

Secondly, the parties have the responsibility to provide evidence to prove the facts on which their claims are based, or to refute the other party's claims. If there is no evidence or the evidence is not enough to prove the claims of the parties, the parties with the burden of proof shall bear the adverse consequences.
