Wharton professor says America should shorten the work day by 2 hours
22 years ago I worked for company that gave us Friday afternoons off.  We worked 8-5pm and on Friday 8-1pm.  That gave employees time to schedule doctors or dental appointments, leave early for the weekend, or run errands.  Best job schedule I ever had. This kept employees at work and not taking time off mid week.  Working with his schedule insured a very productive group of employees.
