April 27, 1825

Journeymen carpenters in Boston went on strike for a 10-hour workday. Required to toil from sunup to sundown, they described their schedule as "derogatory to the principles of justice and humanity." Master carpenters, who controlled the work, defended the long days as "that which has been customary from time immemorial." With the help of businesses and other allies, the master carpenters defeated the strike. By the 1830s, however, the movement for a 10-hour day gained traction in several cities. The federal government implemented it first in the Navy Yard in 1836 and for all public works four years later.
