Clifford “Cliff” Joe Guffey, a dedicated American labor union leader and a tireless advocate for working families and veterans, passed away peacefully on February 21, 2026, at the age of 76. Born in Shawnee, Oklahoma, Guffey's early life was marked by frequent moves due to his father's career as a U.S. Navy pilot, instilling in him a broad perspective and a deep sense of patriotism. He carried this commitment to service throughout his life, believing strongly in the freedoms he defended and ensuring his family understood their importance.

Before his distinguished career in the labor movement, Cliff Guffey proudly served his country as a rifleman in the United States Marine Corps from 1968 to 1970, including a tour in Vietnam. Upon returning home, he began his postal career in 1971 as a letter carrier in Oklahoma City, quickly transitioning to a letter sorting machine operator and joining the American Postal Workers Union (APWU) in 1972. This marked the beginning of a lifelong commitment to improving the lives of postal workers.

Guffey's leadership within the APWU began in 1979 when he was elected president of the Oklahoma City Area Local. His dedication and effectiveness led to a rapid ascent through the union's ranks, serving as Assistant Director and then Director of the Clerk Division, and later as Executive Vice President. In 2010, he achieved the pinnacle of his union career, being overwhelmingly elected National President of the APWU, a role in which he represented approximately 250,000 employees.

As APWU President, Cliff Guffey championed job security for postal workers, fought against subcontracting, and testified before Congress on postal reform, advocating tirelessly to avert post office closures and service reductions. He was also a vice president of the AFL-CIO and co-chaired the Union Veterans Council, consistently prioritizing the issues faced by veterans and working families. Though his tenure saw challenges, including a controversial contract agreement, his unwavering commitment to his members' well-being remained paramount until his retirement in 2014.

Cliff Guffey is survived by his beloved wife of 55 years, Donna Guffey, their two daughters, four grandsons, and a sister. He and Donna made cherished memories at their home on Monkey Island at Grand Lake before moving to Tulsa in 2024. His legacy is one of steadfast advocacy, profound patriotism, and a deep-seated belief in the dignity of labor.
