The 1981 Major League Baseball strike was the fourth work stoppage in Major League Baseball since the 1972 Major League Baseball strike. The strike began on June 12 and forced the cancellation of 713 games (or 38 percent of the Major League schedule) in the middle of the regular season. The two sides reached an agreement on July 31, and play resumed on August 9 with the All-Star Game, with regular season play resuming one day later.
