Boss, you have worked hard, and your dedication to employees is admirable! The teacher didn't shoot your PP, there is no need to shoot it.

Suggestion: Find the right time, for example, someone chases someone with a knife, and the chased person deliberately escapes to the outside, preferably in a crowded street, so that several people who have planned in advance can catch this person in a down-to-earth manner, call the police and let the police send him to a mental hospital for compulsory treatment. In that case, the police are obliged to deal with it. If it is in the internal venue of the enterprise, the police will definitely refuse, will find the leader to sign something, and will find trouble for themselves, so be sure to lead outside!

If you are a fake mental patient, as soon as you go in and see the electric batons, you will immediately raise your hand and surrender. Then you can force the police to further educate and deal with it (detention for 3 ~ 5 days), and he will be honest immediately and will help others turn over a new leaf!

There is another way: find the "ringleader" among them and buy him off secretly, such as being a "security officer" and let him help the unit manage those people to see if the overall situation will improve.

I have seen the above two tricks in similar situations, both of which are very effective!
