After Bush declined to appoint an emergency board to mediate the labor dispute, Congress passed a compromise bill designed to establish a bi-partisan commission specifically to "investigate the labor dispute" at Eastern, but it was vetoed by Bush on 21 November 1989. The following day, the pilots' union voted to end its strike, after about 800 of its members had crossed picket lines, and many others had taken early retirement or gone to work for other airlines. The flight attendants ended their strike the following day, but the machinists continued to strike.
