The Three-Day Week was one of several measures introduced in the United Kingdom by the Conservative Government 1970-1974 to conserve electricity, the production of which was severely limited due to industrial action by coal miners. The effect was that from 1 January until 7 March 1974 commercial users of electricity would be limited to three specified consecutive days’ consumption each week and prohibited from working longer hours on those days. Essential services (e.g. restaurants, food shops and newspapers) were exempt.
