Only in a union environment do work groups general hate each other. Even if they are both union go figure. In the "real world" most people just go to work do their jobs, help each other out regardless of job or title and go home content, the stuff you waste your energy and mind on are truly sad.
The vast majority of unions must have an adversarial relationship these days to keep the sheeple in line. Otherwise the rank and file may question why all the union seems to do is support socialist politicians and anti worker policies.
You are a not paying attention than. Not been watching the OSW movement which is not only socialist but communist and certainly anti-jobs and unions have been right there with them leading the charge. They supported Obama the most job killing POTUS in US history despite his close ties and upbringing surrounded by socialist and communist. Your a fool if you think the modern union political movement is a friend of workers or Americans at all. Why have unions become the single biggest environmentalist in the US next to the far left wackos? Deep seeded concern for the planet? No of course not, they take positions diametrically opposed to their memberships best interest for political purposes only!
Baa, baa, baa!
Pay your dues, march when they tell you , chant your slogans that rhyme and otherwise keep your head in the sand.
What is it like to be an adult that has never thought for yourself?
How is that any different then you mindless, senseless, slogan regurgitating unionista's bashing everything the company does, even when they do something obviously well or correct?
I think this is enough to prove my point.
