IAM union members at Lufthansa Technik Puerto Rico have voted to retain their union representation, defeating a decertification effort led by the National Right to Work Legal Defense Foundation. The vote took place amid ongoing disputes over contract negotiations that have been stalled for nearly three years.
More than 200 aircraft mechanics and related workers at Lufthansa Technik Puerto Rico joined the International Association of Machinists and Aerospace Workers (IAM) in May 2022. Since then, workers have called on management to negotiate a collective bargaining agreement that reflects their skills and contributions. However, according to IAM representatives, management has delayed negotiations and failed to address worker concerns.
In 2023, the IAM requested intervention from the National Mediation Board as a federal mediator. The German union Verdi also urged Lufthansa AG, the parent company of Lufthansa Technik, to help resolve the contract dispute in Puerto Rico.
IAM International President Brian Bryant stated: “Lufthansa Technik must now come to the table ready to negotiate a contract that honors these workers’ skills and contributions. The workers have spoken loudly and clearly: they want respect, they want stability, and they want a fair contract. The IAM will not rest until they get the contract they deserve.”
Craig Martin, IAM Southern Territory General Vice President, said: “This vote is a powerful testament to what solidarity can achieve. Lufthansa Technik workers stood together against outside interference and made it clear that they want a strong union fighting for them at the table. Now it’s time for the company to respect that mandate and bargain in good faith.”
Richie Johnsen, IAM Air Transport Territory General Vice President, added: “Our members in Puerto Rico showed tremendous resolve in the face of intimidation and delay tactics. They know their worth, and they know that union representation is the path to better wages, safer working conditions, and a more secure future. Their unity is inspiring, and the IAM is with them every step of the way.”
Lufthansa Technik Aircraft Mechanic Ilianalyn Delgado commented: “We stayed united because we know what we bring to this company. We keep these aircraft flying safely. We deserve respect, a voice on the job, and a contract that reflects our work. This vote shows we’re not backing down.”
The IAM has called on Lufthansa Technik Puerto Rico management to end stalling tactics and return to negotiations prepared to reach an agreement.
