In 2000 the apathy of the junior vote at US Airways was overwhelming. Scope and other provisions that negatively impacted junior pilots were being voted upon every day.
So we started a little group called "A Unified Front". Printed 500 bag tags that said, "Protect the 1149", started a website, and got the largest turnout of junior pilots at a Philly MEC meeting in years.
You have to campaign for your peer-group. It takes some communication, some drive, and good organizational skills, but it helps.
