How to deal with the person who hides the knife in the smile or loves to sow discord?
It is not difficult to deal with colleagues like a dagger in the heart. On the surface, we should keep friendly relations with him, but behind his back, we should guard against him. All business decision-making reports related to him should hold a meeting and invite relevant people to attend. Other business information is always avoided, and communication with him is limited to business, personal privacy and even other colleagues. As long as everything is reserved, he can't do it to you!
As for those who love to sow discord, the best way is to keep a distance from them outside working hours, and remember to be careful in words and deeds to avoid giving him any "pain". If possible, you can isolate him from other colleagues and leave him helpless.
What about colleagues who are in trouble?
This kind of person is very troublesome and often gets angry because of something. Small things should become big things. When they encounter something or talk about something that has nothing to do with you, don't comment or jump to conclusions. If the incident concerns you, you just need to keep a low profile, and all official documents must follow complete procedures. If you want to make a report, you must report the incident to your superior in black and white and let him decide right and wrong. Of course, don't forget to keep your manners and keep silent afterwards.
