In November 1989, the 8th Court of Appeal ruled that team owners were exempt from federal cartel laws as long as players were properly represented by a union.  In the same year, the NFLPA decided as a union and stated that its union status offered more protection to owners than to players.  The NFL remained without a collective agreement until 1993.  In the last CBA, negotiated in 2011, the agreement stated that the average share of the player should be at least 47 per cent over the next ten years. This time, players will receive 48 percent guaranteed from 2021. It can increase to 48.5, which the NFL estimates will increase players by $5 billion over the next 10 years. After the first two games of the 1987 season, the players went on strike for the free agency.  In response to the strike, the team owners took replacements and continued the regular season after a week. Several well-known players, including Joe Montana, Lawrence Taylor and Tony Dorsett, crossed the picket lines to reintegrate their teams with these new replacements.   On October 15, players voted to end the strike and file a complaint against the restrictions imposed by the free agency in the courts.  In January 1988, Justice David Doty sided with the players and ruled that the non-protection of the first restrictions on refusal and compensation of free agents was not protected by the work exemption from antitrust laws.
 But in July 1988, Doty refused to issue an injunction that exempted players from the restrictions and ruled that the Federal Norris-LaGuardia Act prevented the courts from issuing injunctions in labour disputes.  He called on both parties to return to the negotiating table in preparation for an antitrust process.  Of course, the agreement is much deeper. Many discussions have focused on whether players would get enough in exchange for adding an additional regular season game, amid concerns about its impact on player health. After the players won the Mackey case in court, the NFLPA and the owners agreed on a new CBA that introduced a new system of refusal and compensation to replace the De Rozelle rule.  The new system still limited the free agency of players.  In the court`s decision, it was stated that compensation for draft choices was to be awarded on the basis of salaries received by outgoing independent agents.  The 1977 agreement significantly improved some medical and retirement benefits for players and achieved a neutral reconciliation of all player/club disputes. In 1982, after the first two games of the season, NFL players went on strike again in an attempt to achieve a guaranteed percentage of the club`s and the league`s revenues.  This strike lasted 57 days, making it the longest work stoppage in NFL history at that time.  The strike ended with an interim agreement on 16 November, which included funds to cover the shortfall in players` wages during the work stoppage.  Negotiators signed a new collective agreement on December 5.
