Let me give you an idea. You can install cameras in private places to monitor their work, but this will cause psychological imbalance among employees. The more you do this, the lazier they are. In fact, I also work, and the enthusiasm of employees is easy to improve. For example, your salary is higher than that of similar baths. If it is better, your employees will be very willing to come to work for you. But in contrast, your salary is low, and your employees must be psychologically unbalanced, so they are not active. This means that my salary is good and my salary is high. Leave if you can't do it well. There are still many people who want to work here. This means that, in fact, everyone who comes out to work only looks at whether they are satisfied, and then looks at the salary. I wish you a satisfactory employee as soon as possible.
