Workers call for trade union, why do you surmise employer don't approaching them, because they know workers will benefit
Answers:
Unions are an outdated model that be originally used to protect workers. In this daytime and age workers enjoy more gift to move between jobs/careers and can efficiently come by earnings for production. Unions are extra surrounded by the US anymore - though if I could numeral out a path I would ship them sour to India and Mexico (et. al) to catch the wages up nearby so a smaller amount job would offshore.
No it's because laid-back general public use the Unions to hide from view trailing because they don't want to work!
