British Ryanair pilots will hold a strike ballot to determine whether or not the union will engage in industrial action in response to an ongoing dispute regarding pilots’ wages. In 2017, Ryanair recognized unions for the first time. Since then, the firm has experienced increased industrial action as more pilots begin to organize. The firm has reached agreements with numerous unions, but has failed, thus far, to reach an agreement with British pilots. The union has even accused the firm of using “stalling tactics” in order to delay negotiations.
