Why do property managers always crowd out employees?

If it's a new property manager, send a message. Once every courtier is a courtier, he squeezes out employees, indicating that he doesn't want him, and wants to get rid of him, so that his own people can take office, especially the heads of other departments, and let him take charge.

If he is not the new manager, but has stayed in this management office for a long time, it means that this employee is not good and wants him to leave.
