who came up with 5 day work week
Workweek and weekend
The present-day concept of the 'week-end' first arose in the industrial north of Britain in the early part of nineteenth century[1] and was originally a voluntary arrangement between factory owners and workers allowing Saturday afternoon off from 2pm in agreement that staff would be available for work sober and refreshed on Monday morning.[2] The Amalgamated Clothing Workers of America Union was the first to successfully demand a five-day work week in 1929.
