From the IPA website:
On January 10, 1990, the Independent Pilots Association was founded. It all began in late 1989 when founding fathers Bob Miller, Jim Sutton, Herb Hurst and Rick Erwin handed out union cards in the SDF cafeteria during the night sort. We are grateful for their tireless efforts, which laid the foundation to create what has become one of the strongest, most respected unions in the world.
During these past three decades, the IPA has endured and overcome numerous challenges, some of which threatened our very existence. Without question, the unique challenges faced during 2020 have added another memorable chapter to our rich history. Standing together, we are overcoming these challenges every day, emerging as a stronger and more unified pilot group.
It wasn't easy to start the union. The original founders were under a lot of stress and pressure from UPS but they prevailed.
