As supervisors, do we have an understanding of human capital management and administration?

I have come across certain supervisors that make it very clear that they are happy to superintend work and not the human beings doing the work. The aversions with regard to matters of welfare and discipline are accompanied with dereliction of duty and unfair reference to the mainstream human capital management function. This, in my view, is a travesty.

As long as you supervise people you must have people management skills.

What do you know about human capital management and how do you apply it as a supervisor?
