The latest: An Illinois skier who visited Park City during the holiday filed a class-action federal lawsuit Thursday on behalf of himself and "thousands" of guests, alleging Vail failed to warn customers that a strike was imminent and would affect their visit.

About 200 ski patrollers at Park City Mountain Resort went on strike for almost two weeks during the busy holiday season.

The strike at Vail Resort's largest U.S. ski property lasted nearly two weeks and shined a spotlight on the growing union.
