In 1955, the German Trade Union Confederation, the DGB, called for a five-day week of eight-hour days, a 40-hour week, with full pay. Its slogan for May Day 1955 was 40 Stunden sind genug – 5 Tage sind genug, 40 hours are enough, five days are enough. For May Day 1956, the DGB printed a poster with the line Samstags gehört Vati mir. On Saturdays, Daddy belongs to me. The five-day week then came industry by industry, in coal mining in 1959 and in banking in 1961. The 40-hour week was agreed in printing in 1965 and in the metal industry in 1967.
