Companies do the same? Do they lock their employees out to get them to accept less? No,

The 2011 National Football League Player lockout was a work stoppage imposed by the owners of the NFL's 32 teams that lasted from March 12, 2011, to July 25, 2011. When the owners and the NFL players, represented by the National Football League Players Association, could not come to a consensus on a new collective bargaining agreement, the owners locked out the players from team facilities and shut down league operations. The major issues disputed were the salary cap, players' safety and health benefits, revenue sharing and television contracts, transparency of financial information, rookie salaries, season length, and free agency guidelines. During the 18-week, 4-day period, there was no free agency and training camp, and players were restricted from seeing team doctors, entering or working out at team facilities, or communicating with coaches. The end of the lockout coincided with the formation of a new collective bargaining agreement prior to the start of the 2011 regular season.
