When I first entered the company, it was easy for colleagues to communicate with each other, but there was a person who would tell you all her difficulties soon after she knew you. Such people can't be intimate. She will tell you, or she may tell others. Don't talk to others briefly, and don't be a trash can for others' emotions.
2. A gossip.
Generally speaking, people who love right and wrong must be right and wrong. Such people usually complain and gossip. When you are unhappy with your colleague, he will look at the fire from the other side and not help you. Or spread your behavior to the ears of superiors. Once the superior doesn't see it clearly, your life in the company will be sad.
3. Love people who take advantage of small things.
Some people like to be greedy and cheap, thinking that "stealing is not stealing", they take away the company's property, such as stapler, paper, stationery and other small things. Although it is not worth a few dollars, the boss will never tolerate traitors.
