We were 6 devs on a big project that needed to be completed in 3 months. Probably my first project as a full-stack dev and the work was very demanding.

The senior of my team was a very sharp and energetic, but also a very "in your face" kinda guy. Like, he was cool, but sometimes a little too much to handle for some people.

Anyway, this guy "Senior dev" worked faster (naturally) and harder than the rest of us and was always willing to help if somebody had problems with a framework, tool or other technology. Also, there was this other guy also a good dev (second best I would say) that just hated the first guy's guts for being "rude and obnoxious" as he put it.

One day, the PM and the senior had an argument about a major change that the PM had agreed to (just to save face with the client) that will force the team to come to work on the weekend. In the end he saved us the trouble of going throught that and the PM had to tell the client that the change wouldn't be made. From then on it went downhill for "Sr. dev" in the company. Until one day he was told that his contract was not gonna be renewed.

Short after, he showed some of us a screen cap. somebody sent him of an email from the "hateful" dev to the PM in which he wrote he had heard that the senior guy was leaving and he couldn't be happier because he was "damaging, problematic and a stressful part of his job". That was such a dick move, we thought he should get back at the guy.

So he sent a fake email to the PM using the "hateful" guy's email ID, that read:

"Dear PM. I'm sorry I said those things about 'Senior dev', I guess I'm just mad that he's a better professional than me and mad that I was born with no genitalia".

After the senior dev left I worked on one more project with the "hateful" dev and he was let go mid project for "not being proactive and making little effort on completing the project".
