Well. It's really a good question and absolutely no doubt on how critical unmotivated people could drawback the organization performance and toxic organization work environment.
I think organization leadership team/senior management should investigate the root cause(s) of their people turning unmotivated. It's usually a collective group of causes that turn organization people unmotivated and no one action, idea or button could turn one unmotivated person to a motivated person. In my opinion, leadership team/senior management should do their best in providing the good work environment that help employees got motivated. Of course, no magic action or one way of doing that but small consistent actions will definitely do the change over the time.
That book sounds like it was based off of Deming’s 14 points: Consistency of purpose, institute leadership, drive out fear, and pride of workmanship.
Personal experience confirms what Deming and Pink were talking about. I’ve worked in an environment where the mentality was do what I say and don’t question it. That organization made little to no progress toward any of their KPIs. Whereas another organization I’ve worked for had people first and practiced servant leadership. The latter couldn’t stop their growth even if they tried.
Leadership (not management) makes all the difference in an organization.
