National Hockey League [SEP] Labour issues
There have been four league-wide work stoppages in NHL history, all occurring after 1992. The first was a strike by the National Hockey League Players' Association in April 1992 which lasted for ten days, but the strike was settled quickly and all affected games were rescheduled. A lockout at the start of the 1994–95 season forced the league to reduce the schedule from 84 games to just 48, with the teams playing only intra-conference games during the reduced season. The resulting collective bargaining agreement (CBA) was set for renegotiation in 1998 and extended to September 15, 2004. With no new agreement in hand when the contract expired on September 15, 2004, league commissioner Gary Bettman announced a lockout of the players union and closed the league's head office.
