Who was the principle author of the law that was intended to amend the National Labor Relations Act?
Answer: J. Mack Swigert
The Taft–Hartley Act amended the National Labor Relations Act (NLRA; informally the Wagner Act), which Congress passed in 1935. The principal author of the Taft–Hartley Act was J. Mack Swigert, of the Cincinnati law firm Taft, Stettinius & Hollister.
Historian James T. Patterson concludes that:
By the 1950s most observers agreed that Taft-Hartley was no more disastrous for workers than the Wagner Act had been for employers. What ordinarily mattered most in labor relations was not government laws such as Taft-Hartley, but the relative power of unions and management in the economic marketplace. Where unions were strong they usually managed all right; when they were weak, new laws did them little additional harm.
