What is the treatment of Nanjing Eston Automatic Control Technology Co., Ltd.?

I worked in Ashton General Factory for a period of time, and the company leaders all paid lip service. More rules and lower wages for 30 days a month. After working for 30 days and working overtime every night, the performance appraisal will cost 5000 yuan! Basic salary 1890. If you resign, you will get half of your performance without any subsidy! Private enterprise, big shelf! Anyone can go in.
