Have a competitive relationship
There must be competition in the work, and there will be success or failure if there is competition. With the first place, there will be others behind. In the workplace, everyone has a competitive relationship. Many times, any job or competition needs to be divided into good and bad. If you are the winner, your colleagues are the losers. Do you think he really won't feel bad? This is unrealistic, everyone wants to be that good.
Everyone should have heard of the saying "there are no eternal friends, only eternal interests". It's true. In the workplace, most of the time everyone has interests. Few people will give up their due interests for you. There is no so-called emotion in front of interests, and it is still clear between brothers. Not to mention the fragile colleague relationship. Therefore, in the workplace, where there are interests, don't easily become friends with colleagues. Usually I am very close to you, but when I face the interests, I just want to kick you away.
