Labor Day

Labour day or Labor day is an annual holiday to celebrate the economic and social achievements of workers. Labour day has it's origins in the labour union movement, specifically the eight-hour day movement, which advocated eight hours for work, eight hours for recreation and eight hours to rest. - Wikipedia

Question: What about those working 4 days a week, 11 hours a day with 3 days off? Is there such a thing like eleventh-hour movement? Are they also part of the annual holiday?

Well, just me and my silly thoughts!
