Major League Baseball players are considering a high-stakes legal maneuver known as a “disclaimer of interest” as the December 1, 2026, expiration date for the current Collective Bargaining Agreement (CBA) approaches.
This strategy, which effectively dissolves a union’s status to strip a league of its antitrust immunity, has previously been utilized by players in both the NFL and the NBA to force movement in stalled labor negotiations, Al Bat reported.
The Mechanics of Union Disclaimer
A disclaimer of interest occurs when a union formally ceases to act as the collective bargaining representative for its members. By taking this step, players remove the legal shield that typically protects professional sports leagues from antitrust litigation. This move allows athletes to argue in federal court that a lockout constitutes an illegal boycott or anticompetitive practice rather than a protected labor action.
The tactic carries historical weight in American professional sports. In 1989, the NFL Players Association employed this strategy to challenge restrictive free agency rules, a process that ultimately paved the way for the modern free agency system. Later, during 2011 lockouts, both the NFL and NBA unions utilized the same maneuver to pressure owners into reaching new collective bargaining agreements.
Stalled Negotiations Over Salary Caps
The current tension in MLB centers on the league’s push to implement a salary cap and a salary floor, mechanisms the MLB Players Association (MLBPA) has historically resisted.
On November 3, 2026, the league presented a proposal that would delay the implementation of these financial limits until 2028. The league’s plan suggests a cap of $258.2 million and a floor of $180.2 million, alongside incentives such as a $1 million minimum salary and the removal of the qualifying offer.
The league maintains that this transition period is necessary. “We recognize that the clubs will need an entire offseason to prepare to operate under the salary cap and floor system,” said Glen Caplin, a spokesperson for MLB.
The players remain skeptical of these terms. Bruce Meyer, the interim executive director of the MLBPA, criticized the league’s public messaging during the negotiations.
“Don’t believe their public relations maneuvers — no matter what they say, their ultimate goal is to remake the game under a system that restricts salaries, hinders competition, pits players against each other and does nothing to level the playing field or reduce costs for fans,” Meyer told Al Bat.
Players Face Risks When Dissolving the Union
While the strategy offers potential advantages, it is not without peril for the players. Dissolving the union means surrendering the protections and benefits afforded by a formal collective bargaining agreement. Legal challenges can persist for years, and courts do not always halt lockouts during the proceedings. In 2011, for example, a court allowed the NFL lockout to continue despite the union’s disclaimer, citing the Norris-LaGuardia Act.
The legal environment for baseball is distinct due to the Curt Flood Act of 1998, which removed the league’s antitrust exemption regarding player employment. This legislation makes the disclaimer of interest a more viable tool for MLB players than it would have been in previous decades, as it explicitly provides a pathway for antitrust claims that were previously barred.
Potential Structural Changes
The economic impact of the league’s current proposal is significant. According to league figures, the plan would require eight teams to reduce their payrolls by a combined $528 million, while twelve teams would be expected to increase their spending by a total of $636 million. This reallocation reflects the depth of the change the owners are seeking to impose on the current financial structure of the game.
As the December 1, 2026, deadline nears, both sides remain entrenched. The future of the league’s economic system may depend on whether the MLBPA decides to trigger this legal option or if a compromise can be reached at the bargaining table before a potential lockout begins.
