Every five years or so, Major League Baseball and the MLB Players Association sit down to negotiate the rules that govern professional baseball. The result is the collective bargaining agreement — commonly called the CBA or, more formally, the Basic Agreement. It is the single most important document in the sport, and almost everything fans argue about (salaries, free agency, the luxury tax, tanking, competitive balance) is controlled by what’s inside it.
The current CBA covers the 2022 through 2026 seasons. It runs 426 pages. It expires at 11:59 PM ET on December 1, 2026, and what comes next could reshape how baseball works for years to come.
The CBA is not just about money, though money is at its center. It governs the minimum salary every player must be paid ($780,000 in 2026), the rules for free agency and service time (six years of major league service to reach free agency), the structure of salary arbitration (available after three years for most players), and the luxury tax thresholds that penalize teams spending above certain levels.
It also covers revenue sharing between teams, roster sizes (26-man active rosters, 40-man rosters for competitive balance tax calculations), the amateur draft, international signing rules, meal allowances, travel protocols, spring training conditions, and dozens of other working conditions. If it affects how players and teams interact, the CBA likely has a section on it.
Fans don’t read 426-page labor agreements, and nobody expects them to. But the CBA shapes the game fans watch in ways that are hard to overstate. Whether a rebuilding team is required to spend a minimum amount on payroll depends on whether there is a salary floor — and right now, there isn’t one. Whether a star player can leave his team at age 27 or is locked in until 30 depends on service time rules. Whether the Yankees and Dodgers can outspend everyone else by $200 million depends on how the luxury tax is structured.
When fans say “baseball is broken,” they are usually describing a problem the CBA either created, allows, or has failed to fix. The negotiation is where those problems get addressed — or don’t.
The first Basic Agreement was signed in 1968, making it the first collective bargaining agreement in professional sports history. Since then, every CBA cycle has involved contentious negotiations, and many have resulted in work stoppages. The 1994–1995 strike, fought primarily over the owners’ push for a salary cap, remains the most damaging labor event in American sports.
The most recent CBA was ratified in March 2022 after a 99-day lockout. Key changes in the current agreement include a $50 million pre-arbitration bonus pool for top young players, expanded playoffs (12 teams), a pitch timer, the universal designated hitter, and a six-pick draft lottery. The luxury tax base threshold was set at $230 million in 2022, rising to $244 million in 2026.
The next round of negotiations is expected to be the most contentious in decades. MLB owners have signaled their intention to push for a hard salary cap — something the MLBPA has never accepted. Commissioner Rob Manfred reportedly visited clubhouses during the 2025 season to make the case directly to players, with mixed reception.
Other likely negotiation topics include an international amateur draft, changes to free agency eligibility (MLB has proposed tying free agency to player age rather than service time), expanded revenue sharing, minimum payroll requirements, and the structure of the luxury tax. Any or all of these could change — or stay exactly the same — depending on how negotiations unfold.
In MLB Strike 2027, you negotiate the CBA yourself. The game puts you in the Commissioner’s chair and asks you to set the salary cap, salary floor, luxury tax, revenue sharing, minimum salary, and free agency rules — balancing the demands of players, owners, and public opinion. Every choice shifts three approval meters, and pushing too hard on any issue can trigger crises, media backlash, or a collapse in negotiations.
The standalone Salary Cap/Floor Tool lets you skip the story and jump straight to the numbers: set a salary floor, luxury tax threshold, and hard cap, then see which side hates your proposal most.
