In fact, it is because newcomers are not as stable as in earlier years. Now with the improvement of people's living standards, everyone will have some money at home, so that everyone can't solve the problem of food and clothing, and there is no pressure on mortgage and car loan. So in their work, most of them are directed at how happy they are and how they work. In the workplace, they can't stand any injustice or scolding from the leaders.
Another is that many old employees have a heart-to-heart talk for a period of time, and then the newcomers leave, and then the newcomers join and continue to teach. This repeated teaching has changed the mentality of many old employees, and they are not as serious and responsible as before.
The second is that bringing new people will increase the workload for no reason.
Nowadays, most people are indifferent in the workplace, and there are few nice people. Everyone is very busy at work. If their work is not finished, how can they make time to bring new people? So this is also a very realistic problem. Whether it's bringing new people or meeting people, everyone has their own selfishness. Some people just think that I haven't finished my own things and I can't help others, so I will go away.
