What things in the workplace will make you unbearable to resign decisively?

That was three years ago. At that time, I worked in a company. Every time I get off work at 5: 30 pm, there are four people in the office, plus five leaders. Sometimes the leader is here and sometimes he is not, but whether the leader is here or not, it seems that it is not time to get off work. What should everyone do when they are sitting at their desk? I just arrived at the company, and I don't know what happened. I didn't dare to leave until everyone left, but my mother just stopped by to accompany me after work at one o'clock. Later, I secretly asked my colleague that she was here to work. That's it. This is the rule. Oh, my god, why did it say that you should get off work at 5: 30 when recruiting? Can't you leave after a day's work? After a few days of persistence, I really don't think it is necessary. Plus, I didn't take the bus with my mother and wasted a lot of time squeezing the bus myself, so I started to take the lead and stay at least for a while before work. Since then, the leader has started to find fault and sent you out to do things you shouldn't do. I have also been isolated by my colleagues in the whole office. I only worked there for less than two months, but only got a month's salary. Then I went to two companies. Usually I get off work at one o'clock. Even after I finish my work, no one gets off work at one o'clock, so I am determined to work within the system. Now I am sure to get off work at one o'clock every day in the system, so I can have some time of my own and do something I want to do. I think some private enterprises should strictly follow the labor law to make young people fall in love with their jobs.
