No question it's Doc's business! I do not know how Doc manages his business, so what follows do not (necessary) apply to him or his business...
I'm a strong believer that when in position of any authority at a work place, best way to manage people is by being a good leader. Too many people make the mistake to confuse the two, however one can be an efficient manager without being a good leader (as the opposite is true too). Being a good manager requires you to say the things right whereas being a good leader requires you to say the right things. In order to say the right things, one needs to seek constructive dialog, never be emotional or reactionary and know when to listen and when to speak. All this requires compromises. On the other hand, one can always manage with an iron fist and fire people at will, but that does nothing good to the business in the long run.
Again, I know nothing about what happened, the context or the background of Doc's business, so I'm not judging anyone...
