中华儿女多奇志

The celebration of Labour Day has its origins in the eight hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest. On 21 April 1856 building workers around Melbourne, Australia stopped work and marched to achieve an eight hour day. Their direct action protest was a success, and they are noted as the first organized workers in the world to achieve an eight hour day with no loss of pay, which subsequently inspired the celebration of Labour Day. http://en.wikipedia.org/wiki/Labour_Day
