The very idea that you think a union "mob" is attempt to "strongarm" their employer is beyond idiotic. You do understand that employers have ALL THE LEVERAGE and individual workers have absolutely NO POWER without unions, right?
You have a naive notion of how unions work lately. Ask any citizen of Toronto last month who were strong armed and threatened by their employees who collect the garbage. $25.00 an hour and banked sick days that are cashed out when you retire are not good enough for these guys.
