When I did my MBA at Fisher (Ohio State 2018-2020) this definitely wasn't the case. We actually spent considerable time talking about how to get the most out of your team and how dumb of an idea it was/is to treat employees poorly. Many of our in-class discussions that revolved around this topic focused much more on treating employees well and how dangerous bad corporate culture and out of touch leadership was. Many of my classmates came from prior working backgrounds in various fields, however, so perhaps that leads to a different culture at the b-school.
