A great look at the some of the dark side of the Wellbeing industry, the history of health and psychology in relation to management theory, and how to get the most productivity out of people.
[It's quite long but you may learn a lot from reading this one. Inc. some particular stories in the UK gov too. From the book The Happiness Industry]
The general sense I get from this piece is a look to new 'cures' for employee disengagement through attitude adjustment, recategorization of worker issues/challenges, and generally focusing on removing/firing the disengaged from the workforce.
There is also a good bit about the history of Happiness research from the 1920s, the notions of Health and Wellbeing, in relation to Management theories and productivity.
