Not so fast. I "saved" guys from being fired by asking to be more patient with them. The last one was not in my team as I moved out to lead another team. Turned out the guy did not please an influencial team member, who then complained about him. What I saw instead was a young silent guy, given boring work and was longing for more interesting work. A tad later he took ownership of a neglected project, completed it and made a name of himself.
It takes considerably more effort and skill to treat colleagues as humans rather than "outputs" or ticket processing nodes.
Most (middle) management is an exercise in ass-covering, rather than creating healthy teams. They get easily scared when "Jira isn't green", and look someone else to blame for not doing the managing part correctly
