There’s big money at stake for unions at Delta Air Lines, Inc—over $22 million in annual union dues. As the only primarily union-free major airline Delta’s pilots are unionized, unions have long targeted the Atlanta-based carrier. However, now, with the National Mediation Board members being controlled by unions, as well as Delta’s recent merger with unionized Northwest Airlines, the unions have declared it open hunting season on Delta. So far, however, the unions have lost eight out of the eight elections they’ve called for—and now are going to rely on the union-controlled NMB to overturn the results so they can hold rerun elections.
