What I’m saying is not criticism, I think the word enemies is quite isolating and too negative. It’s definitely true that every place with more than one human has inter-personal motivations and constraints, but I think they often can be fluid and non personal, someone contested the position you got but after the position was granted they realized they’re very much ok with not spending extra work time in the new job for example, or the employee that contested you to the promotion just wanted the raise or the ability to influence more in the company and you didn’t take their dream job. In some of those cases I found I can plaster my coworker name in large font on any work we did together or delegate to them tasks that they really wanted to, and I could win their trust and cooperation even though I got the promotion or something of that sort. It’s super subjective and my own personal experience
