You'll rarely see union shops/workers doing work in the private sector. Labor is just too expensive.
Every union rep I ever had forced upon me was bar none the shittiest, laziest, whiniest guy on the job. Never gave a shit about the work or helping other solid employees complete tasks. "Not my job," they'd inevitably say, while any other employee usually had no problem helping out.
To a man, all they talked about was "our rights," "our breaks/lunches," "our contracts," "our negotiations," "our grievances" - never once "our responsibilities." These were workers/reps, mind you; utterly useless pieces of shit, decades worth.
Never once saw them defend a decent worker, either; because good workers rarely, if ever, needed representation. Always just the other worthless malcontents who shoulda been fired anyway.
