KARAHALIOS filed a lawsuit against both DLI and the union, alleging that the union breached its duty of fair representation towards him as a non-member.

The case made its way to the Supreme Court of the United States, where the court had to determine whether KARAHALIOS had an adequate administrative remedy available to him.

KARAHALIOS' experience as a non-union member within a unionized bargaining unit shed light on the unique challenges faced by such employees in navigating labor disputes.
