Where can I complain if the unit system is unreasonable?

Legal analysis: If the unit system is unreasonable, you can complain to the local labor bureau or the labor law enforcement supervision brigade. The company system must be voted by all the staff and workers' congresses to be effective. If it is not voted or publicized to the workers, the workers cannot abide by it. The employing unit shall, in accordance with relevant laws and regulations, establish and improve labor rules and regulations in accordance with the law to ensure that workers enjoy labor rights and perform labor obligations. The employing unit shall publicize or inform the rules and regulations and major issues directly related to the vital interests of workers.
