Pilot unions are organizations that represent the interests of airline pilots. They negotiate contracts with airlines, focusing on issues like pay, working conditions, and job security. By banding together, pilots can have a stronger voice in discussions with management, ensuring their rights and needs are addressed. These unions also provide support and resources for pilots, including legal assistance and training programs. They play a crucial role in advocating for safety standards and regulations within the aviation industry, working alongside organizations like the Federal Aviation Administration (FAA) to promote safe flying practices.
