The Longsh*remen's Union is the worst, in my opinion. Even, the Teamsters won't strike or refuse to deliver when the troops are the receipient of their loads. The Longsh*remen struck in the middle of WWII and caused backups in supplies to the troops During Nam, their strikes caused shortages in ammo, M-16 magazines and rations, They were the main reason we ate rice and chicken for two meals a day for months.
I have to associate with them because of my profession, but its like being the guy who milks snakes to make anti-venom. You don't like the critters but you have to deal with them.
