On Wednesday, Columbia’s Supreme Court confirmed a ban on strikes among air traffic controllers and pilots. The ruling was in response to a massive strike at Avianca, the country’s largest airline. The ruling allowed Avianca to fire 700 unionized pilots who participated in the two-month strike after failed negotiation attempts. The airline said that they had lost $47 million as a result of the strikes. The union has accused the massive airline, which conducts 800 flights a day, of being a monopoly. Nevertheless, the high court sided with the airline giant and banned any future strikes by pilots or air traffic controllers.
