A man who feels he was both needed, and thinks the way forward is to fire members of his team. The trouble is, the problem is in my life I always see a person getting fired and the solution remaining, the problem being a process and an inability to both see and be able to resolve said issue. The horror here being both the problem remains and youve been unethical to fire someone who did not deserve it. Which will only create problems down the line. I believe this is why I feel if I was ever in the position where someone I hire is not right, I continue trying to make it work until I have tried many different solutions. If it still fails, I tell them they are great in they ways they were and explain I want to part ways, and I make sure expectations are made. My only experience has been with short contracts, but if I wanted to part with someone who I was sure was a problem I would not even consider trying to within a 2 year period, its just unethical. If I cant make it work within 2 years, well then we all tried. I dont know if this is the right approach but I believe it would both help in giving time to find and fixing the right problem, the right way. tldr; firing is not cool
