I always hated this side of “communication, teamwork, and personality” early in my career. I thought those soft skills were overvalued by people who weren’t good in their technical skill.
Now that I’ve been a senior engineer for a while, I can say the soft skills are just as important as the technical skills. It sucks leading people with bad attitude and those whom we have to babysit all the time.
Sounds like a breach of contract, which is a civil matter.
