As we approach Labor Day weekend – a time set aside to honor the contributions and achievements of American workers – it is fitting to reflect on the indispensable role of the National Nuclear Security Administration (NNSA) workforce. Our mission of ensuring the safety, security, and effectiveness of America’s nuclear deterrent is critical to our national security. This vital work is not merely a collection of tasks; it is the culmination of dedication, expertise, and relentless effort from thousands of individuals across our sites and laboratories.

The NNSA workforce is a diverse tapestry of scientists, engineers, technicians, administrative professionals, skilled tradespeople, security personnel, and support staff. Their collective brilliance drives innovation in complex scientific challenges, meticulously maintains highly specialized infrastructure, and rigorously upholds the highest standards of safety and security. From fundamental research that pushes the boundaries of knowledge, to the precise execution of operational requirements, every member plays a vital part in safeguarding our nation.

Labor Day offers us an opportunity to pause and acknowledge the profound impact of this committed workforce. Their daily efforts, often unseen by the public, are the bedrock upon which our national security rests. It is through their sustained commitment to excellence that the NNSA continues to meet evolving global challenges and maintain a credible deterrent in a complex world.

The nature of our work demands not only technical proficiency but also an unwavering commitment to protect the American people.  The NNSA workforce embodies these principles, demonstrating a profound sense of responsibility and patriotism that goes beyond the 9-to-5 demands of a job. They are stewards of a vital national capability, and their dedication ensures continuity and reliability for generations to come.

As we enjoy this Labor Day weekend, we extend our deepest gratitude to every member of the NNSA workforce. Your expertise, your sacrifices, and your unwavering commitment are the true strength of this organization and a testament to the enduring spirit of American labor. Thank you for your essential contributions to national security and our country.
