The words 'rest and recreation' are usually associated with the military,where soldiers on leave have down time in order to recharge their batteries. This time was believed to have helped relieve the tense situation that they were under, and ensure that they returned to peak performance.
Interestingly, this notion was instilled in a work crew within one of Henry Ford's factories. This was a very strict routine, where the maintenance staff, were required to spend a required amount of time, within a designated recreation room. They were also paid for the time they spent there, providing it was spent in the designated room only.
This carefully planned set up, involved the use of a red light coming on at the designated recreation time, where production on the assembly line stopped along with payment, temporarily whilst the workers had their required recreation period.
The effects of this, encouraged better workmanship and also ensured more productive labor.
Forward thinking, Henry Ford was one of the first companies, who introduced the five day working week. Interestingly, he Also instilled these values in his son, who was the Company's president in 1922 who stated that:
“Every man needs more than one day a week for rest and recreation….The Ford Company always has sought to promote [an] ideal home life for its employees. We believe that in order to live properly every man should have more time to spend with his family.”
