Economist, September 2016

A large American health-care provider, Ochsner Health System,
introduced a rule that workers must make eye contact and smile
whenever they walk within ten feet of another person in the
hospital. 

Pret A Manger sends in mystery shoppers to visit every outlet
regularly to see if they are greeted with the requisite degree of
joy. Pass the test and the entire staff gets a bonus—a powerful
incentive for workers to turn themselves into happiness
police. 

Companies have a right to ask their employees to be polite when they
deal with members of the public. They do not have a right to try to
regulate their workers’ psychological states and turn happiness into
an instrument of corporate control.
