when did the 10 day disabled list start
Disabled list The categories and variety of disabled lists have changed numerous times over the years. The 15-day disabled list was introduced in 1966, joining 10-day, 21-day and 30-day options, and the 60-day disabled list in 1990. Prior to 1990, the number of players who could be placed on each list was limited, players with major league contracts were not allowed to go to the minor leagues for rehabilitation, and there was less flexibility about when they could return to action. The 10-day disabled list was dropped in 1984 but restored for the 2017 season (replacing the 15-day option), and the 21-day and 30-day options were dropped in 1990 with the introduction of the 60-day disabled list.[9]
Workweek and weekend In 1908, the first five-day workweek in the United States was instituted by a New England cotton mill so that Jewish workers would not have to work on the Sabbath from sundown Friday to sundown Saturday.[9] In 1926, Henry Ford began shutting down his automotive factories for all of Saturday and Sunday. In 1929, the Amalgamated Clothing Workers of America Union was the first union to demand a five-day workweek and receive it. After that, the rest of the United States slowly followed, but it was not until 1940, when a provision of the 1938 Fair Labor Standards Act mandating a maximum 40-hour workweek went into effect, that the two-day weekend was adopted nationwide.[9]
