Over 5,000 British airport workers voted to hold three strikes in January, endangering air travel for millions. The strikes are meant to protest a stop to the union's final-salary pension plan, which union members say will threaten the benefits of current employees. The strikes would be held January 7th, 14th and 17th, lasting 24-48 hours each.
