Teamsters went on strike at UPS and IPA supported them by not crossing their picket lines. IPA asked other pilot groups to honor the Teamster picket lines as well. Evergreen pilots refused to fly any UPS work during the strike even though threatened by management. Most of the Polar pilots also refused but some did fly UPS. ALPA determined that because it was Teamsters strike they would fly UPS hence Atlas and NWA were on the SDF ramp with Polar. Angryblackman said Evergreen pilots were whores and did not have a "real" union. My point is that all unions, real or not, do not always do the right thing. Self interest gets in the way. By the way, the Captain on the first Polar flight into SDF that day was an ex-zoner and a friend of mine. He is still my friend.
