union jobs... many of them for decades you gotta be in family, or hookups, be already dating their daughter, 'look' like em and talk like em, even pay them a 'tip' as part of the whole deal...
thats the case for janitors, commercial sanitation, butchers, contractors, electricians, utility workers like telco workers, water, gas, electrical..
autoworkers dont fall into the category as much i'd say history has dictated...
