Early Closing Association
The Early Closing Association was formed in the United Kingdom in 1842 or 1843 to control the hours of labour in retail shops, and to abolish Sunday trading. It was promoted by Samuel Carter Hall, George Dawson and John Passmore Edwards, among others. Half-day early Closing was not finally won until 1912. Victoria (Australia)
