Simple, Right to Work Laws
More companies like Toyota, Honda, Nissan, BMW, Bridgestone and Boeing are serving their employees well with right to work states and laws.
Good example here and here
Less than 7% of the private sector working employees is a union member, so you have to ask yourself, how do the nonunion workers survive and get along without the union?
Then there's the public union and the changes that are coming because of union greed which hasn't helped the middle class like some claim.
"Wisconsin’s public employees are leaving their unions in droves, which should be no surprise: With passage of Act 10 in 2011, public unions in the Badger State lost many of their reasons for being. The “budget-repair bill” pushed through the Legislature by Republicans and signed into law by Gov. Scott Walker limited bargaining to wages only, and then only up to the cost of living; it also required unions to recertify each year and barred the automatic collection of union dues. Relying on federal financial records, the Journal Sentinel’s Dan Bice found union membership has declined by 50% or more at some unions, including the American Federation of State, County and Municipal Employees District Council 48, which represents Milwaukee city and county workers. It has gone from more than 9,000 members and income exceeding $7 million in 2010 to about 3,500 members and a deep deficit by the end of last year."
