Is the salary of property personnel too low?

Take my smart person fit experience as an example, one is Binjiang Property and the other is Greentown Property. Although they are all operated by subsidiaries, there is too much difference in salaries between the two companies. Let's talk about the Greentown property in Zhengzhou. The contract was signed by Tianjiang Security Company, 12 hour high temperature subsidy, attendance award and overtime pay of 5200+. In Hangzhou Binjiang Property Company, the contract was signed by a coastal company. The first two or three months' probation period was 4,500 yuan, including various subsidies, and then it was 4,500 yuan. If the salary of property personnel is low, it still depends on the company. If the company is black, it is normal to deduct half of Party A's salary. These are two specific companies, which also originated in Hangzhou, and the treatment is very different from the company's formality. It can't be said that the riverside property is not formal, only how much employees pay.
