Why do real estate and precious metals companies recruit people every day?

I work in real estate. Let me tell you something about real estate. The stability of real estate sales staff is not high, and they often change jobs. Small real estate projects, the site has just begun to recruit people, the sales staff left before the opening, and the most profitable two or three months after the opening. After a few months, all the necessary things have gone, and the new employees have left after staying for a month or so. Housing developers can replenish staff at any time. . Large-scale real estate, sales staff is not much, almost a few hundred people. In the eyes of outsiders, their sales are hot and their commission should be high, but this is not the case. Not every employee can make money, only a few people make money, and the last elimination system and task system are implemented. Those who can't meet the requirements will have to leave. Even the sales champion will be eliminated if something goes wrong. . For the intermediary staff of second-hand houses, there are many cases of frequent turnover, such as fatigue, failure to make orders for a long time, changing careers to make money, or starting guerrilla warfare on their own, and they are very familiar with the process (since they do not rely on the company to take orders themselves). Wait a minute. . . When the turnover rate of my previous enterprise was the highest, 80 people were newly recruited and trained, and after half a month, 16 was left.
