The first two paragraphs of that article are a wild incoherent ride, mixing all kinds of things, that have very little to do with each other (feel slighted [...] even the slightest mistreatment [...] failed to deliver birthday greetings on time)

Regardless of the analysis and without having read the study, I agree with the sentiment in the headline and it's sad agreement that matches my experience: Making employees feel not slighted works really well – for both the company and the employee. It does not require that you respect anyone, and actually often runs counter it.

Once you figure that out as an employer, I can see why you would chose to just get better at fooling and distracting people.
