It's not the author's conclusion, but this is basically my fantasy ever since watching Billions with Wendy Rhoades's character. In that show, Wendy is a performance coach working for a hedge fund whose job is to emotionally pump up the people who work for the hedge fund. The hedge fund employs her because (leaving aside the soap opera dynamics for a second) it recognizes that emotional support is both (a) necessary for fully realizing the potential of their knowledge workers (b) not something that every employee is naturally gifted at providing, neither at work for their colleagues nor in their personal lives.
More companies should employ such coaches and schedule regular sessions for all their employees. If everything's great, then great. If not, it's definitely cheaper than employee churn.
