I'm 100% in favor of "checking out mentally". Only I describe it differently. When you start insisting on what's good for the business and your employer disagrees, there's only so far you should go, because in the end they're paying you to do what they (possibly unreasonably) want. It's okay to push back against micromanagement, but that should be viewed as a selfish struggle for better work conditions (or better pay to compensate), not a selfless struggle to make the company better.
