What is the most taboo to get along with colleagues?

What is the most taboo to get along with colleagues? When I get along with my colleagues, I think the most taboo is insincerity. Being able to work together, I often say that being friends together is at the same time, and we should be honest with each other. If there is insincerity, then this period of time will be overshadowed, and the relationship between the two people will gradually become awkward and they will not feel so harmonious. I always feel that it is also a fate for us to work together, so that we can get to know each other and get along with each other day and night. After a long time, you will feel deeply. After a long time, you will feel like a family. If you feel this way, no one can avoid stumbling. Since we are looking for colleagues and friends, we should understand each other, care for each other and help each other. Not to speak ill of you behind your back, not to gossip about you behind your back. I think this is a matter of principle. My principle is to be sincere to the people around me, and to live in harmony with my family, relatives and friends. If anything happens, everyone will lend a helping hand and help each other. But sometimes many people don't think so. They just feel good with you. If you need him, you will run away, even joke, laugh at and vilify others behind your back, just to raise yourself. I think this is very bad, and it is also a taboo in the workplace. Don't be jealous of others in the workplace. Work hard at that time. If there is room for promotion at work, there will inevitably be such competition, and some people will inevitably have some comparisons. Envy others, and finally hurt yourself, don't be special to yourself, and don't let others dislike you!
