At the start of season 14, Hank is retired from which company?

At the start of season 14, Hank is retired from Strickland Propane.

Strickland Propane is the Arlen business where Hank spent most of his working life selling propane and propane accessories. He began as an assistant manager under Buck Strickland and treated the job as a source of pride, stability, and personal identity.

The Hulu revival's time jump places Hank and Peggy after a period living in Saudi Arabia. When they return to Arlen, Hank is retired from Strickland Propane and finds that both his hometown and his family have changed. His retirement helps create the season's central tension: a man defined by work must adjust to a new stage of life.

The other options are businesses or organizations from the show's world, but they are not Hank's former employer. Dale's Dead Bug is Dale's pest-control business, Mega Lo Mart is a rival retail chain, and Aramco is associated with the family's time abroad.
