In May, of 1902, 1500,000 coal miners went
on a strike demanding for their union to be recognized, from the United
Mine Workers; a 20-percent increase in pay and a nine-hour workday.
All of the coal mine owners refused to negotiate, so the strike dragged
on for five months with no hope of settlement. The nation was going
through a severe coal shortage, while winter was approaching.
In October, Roosevelt asked the
owners and miners' representatives to come to Washington D.C. Since
the owners still refused to negotiate, Roosevelt said that he would
appoint an investigative commission and, threatened to use the U.S Army
to run the coal mines. At the same time, Roosevelt persuaded the financer
John Morgan to talk to the owners of the mine. He got them to agree
to arbitration, and they asked Teddy to appoint a commission. Then the
miners returned to work. The following year, the commissions report
led to the adoption of a nine-hour workday, a ten percent increase in
salary, and a process for negotiating disputes within the industry.
