On Jan. 5, 1987, NATCA filed an election petition with the Federal Labor Relations Authority (FLRA) to be the sole bargaining agent for all Federal Aviation Administration (FAA) operational GS-2152 air traffic controllers. The proposed union needed 3,750 signatures — 30 percent of the workforce — but was able to submit 5,800 signatures, or 46 percent. On March 4, 1987, the FLRA scheduled an election to decide whether NATCA would represent the nation’s controllers. On June 11, 1987, more than 80 percent of all controllers voted in NATCA’s certification election. Seventy percent approved the union as their sole bargaining agent.
