That "imaginary monster" that unions have been fighting for a very long time is none other than your beloved right wing republican servants of the wealthiest people in this country. In 1947, Taft-Hartley was forced upon us by a Republican controlled Congress determined to control union power in this country. Taft-Hartley amended the National Labor Relations Act of 1935 by eliminating the closed shop and creating the agency fee, which permitted members to pay that portion of dues that was strictly related to the cost of representation, and not for the union's political activities or organizing expenses. Now, why do you suppose that a Republican controlled Congress would have an interest in curbing the political activities of unions?
Taft-Hartley also provided a loophole, allowing states to do away with agency fees altogether, if that was their desire.That loophole is what we now know as Right To Work laws, laws that permit non-union employees to continue to receive all the benefits of union representation and protection without having to pay one cent in return for those benefits.
Right To Work laws haven't always worked out the way the respective states had hoped. Economists Gordon Lafer and Sylvia Allegretto's review of Oklahoma's Right To Work Law was published by the Economic Policy Institute. Right To Work in Oklahoma was adopted in 2001 and reviewed by Lafer and Allegretto in 2011. Rather than increasing job opportunities, Oklahoma saw companies relocate out of state during that period. In high-tech industries and service industries dependent on consumer spending in the local economy, the law appears to have damaged growth. At the end of the decade, 50,000 fewer Oklahoma residents had jobs in manufacturing and there was no evidence that the legislation had a positive impact on employment rates. In an interview, State Chamber of Commerce President Fred Morgan, a proponent of RTW, couldn't point to any specific companies that located or added jobs in Oklahoma because of the law.
The only credible arguments for Right To Work is that these laws have the effect of weakening unions - and weakened unions tend to be good for business...or at least the owner of the business. So, at least in Oklahoma, the efforts of a handful of greedy Republicans in 1947 served only to benefit a handful of greedy Right To Freeloaders 64 years later.
