Managers of every kind have to deal with personnel, meaning humans, and this is a huge part of what they have to accomplish. They divide their time between humanistic goals and project goals, and it's very squishy.

Managers have to devote a certain amount of time to understanding you and your influence on the process and your mental state.

Managers have to have influence with other people. They build relationships and they form a big picture about the work being done and the timelines imposed and the human assets they have to motivate to meet the important goals imposed by the business.

You've heard all this before but it's a very squishy job. There is no template for it. Management is very, very difficult to do.
