1. A colleague who stabbed in the back Aesop once said: "People who betray their companions often destroy themselves together unconsciously." This famous saying also applies to workplace betrayal. The workplace is like a turbulent river and lake, full of all kinds of people, and those legendary backstabbing stories are countless in reality. Such colleagues make friends with others on weekdays, but at some point in the future, they will "rebel" and vilify the professionals who trust them. In the face of such colleagues who may harm others but not benefit themselves, professionals are hard to guard against. Only by always paying attention and acting cautiously can we avoid being maliciously hurt by such colleagues. Second, colleagues who blame the pot are not uncommon in the workplace. Colleagues shirk their responsibilities and smash pots at will, which is a fatal disaster area. No one wants to be this "back-burner". When the team needs the cooperation of such colleagues, they are opportunistic, and when the company rewards their achievements, they are too active and seek rewards in vain; When you encounter setbacks in your work, you pass the buck and label it at will. As individuals, professionals should not only enjoy the corresponding salary, but also bear the corresponding responsibilities and pay the corresponding price after making mistakes. Interpersonal relationships in the workplace are very subtle. In the face of this strange colleague, it is not enough for professionals to just learn to refuse. Only by broadening their horizons, expanding their pattern and learning to handle relationships flexibly can this problem be completely eliminated from the root. Third, negative colleagues in the workplace, a positive and optimistic attitude can help us face work and life with a better attitude, but there are often negative colleagues around us. They are like "spiritual garbage dumps" at work. The negative emotions of pessimism and world-weariness overflow like water, constantly creating negative magnetic fields. It can be said that no matter what happens, as long as it persists in them, it will turn into a gloomy cloud. Such colleagues seem to avoid it, but in fact, in the same working environment, emotions and ideas are beyond the individual itself and are basically inevitable.
