How to avoid staying up late and working overtime?

This is actually very simple. As long as the workload during the day is increased and the efficiency is improved, there is no need to increase it at all. Many companies have an overtime system, saying that employees can work overtime if they can't finish their work. Some employees may take advantage of this loophole to name their work, but they should postpone it until overtime, because in this case, the overtime pay will be more. In fact, staying up late and working overtime is particularly bad for their health, so I think as an employee, it is a matter of money. First of all, you must consider your physical condition. At this time, you should improve your work efficiency during the day, and you don't have to work overtime if you finish enough workload.
