1981 Major League Baseball strike

The 1981 Major League Baseball strike was the first work stoppage in Major League Baseball since the 1972 Major League Baseball strike that caused regular season games to be cancelled. It was the fourth work stoppage since 1972, but actions in 1973, 1976, and 1980 cancelled no regular-season games. The strike began on June 12 and forced the cancellation of 712 games—nearly 34 percent of the Major League schedule—in the middle of the season. The two sides reached an agreement on July 31. Play resumed on August 9 with the All-Star Game; regular-season games resumed the following day.

An estimated US$146 million was lost in player salaries, ticket sales, broadcast revenues, and concession revenues. The players lost $4 million a week in salaries while the 30 owners lost a total of $72 million.
