Excerpt SEC 10-Q Oct 31, 2024 pg 53

PEOPLE AND LABOR

A significant increase in labor costs or unsuccessful attempts to strengthen our relationships with union employees could adversely affect our business and results of operations.

Labor costs remain a significant component of our total expenses. In addition to costs associated with represented employee groups, labor costs could also increase for non-unionized employees and via vendor agreements as we work to compete for highly skilled and qualified employees against the major U.S. airlines and other businesses in a competitive job market. Labor costs have recently increased significantly driven by inflationary pressure on wages.

Ongoing and periodic negotiations with labor unions could result in job actions, such as slow-downs, sick-outs, or other actions designed to disrupt normal operations and pressure the employer to acquiesce to bargaining demands during negotiations. Although unlawful until after lengthy mediation attempts, the operation could be significantly impacted. Although we have a long track record of fostering good communications, negotiating approaches, and developing other strategies to enhance workforce engagement in our long-term vision, unsuccessful attempts to strengthen relationships with union employees could divert management’s attention from other projects and issues and negatively impact the business. In addition, our bargained-for labor agreement terms for flight crew are increasingly coming into conflict with state and local laws purporting to govern benefits and duties.
