Shikha Dalmia, writing in Reason ("Are Right to Work Laws the New Slavery?," April 26), dismisses most union objections to "right to work" laws. But she concedes that on one issue - the requirement that unions provide representation for scabs who don't pay dues - unions are "on more solid ground."

But, she continues, unions themselves are partly to blame. "They are required to represent all workers in exchange for monopoly rights over collective bargaining in the workplace. That is the Faustian bargain they made in the Wagner Act."

The problem is that she makes this sound primarily like a perk for the unions. She neglects to mention its value to employers, or more generally the way Wagner reflects the interests of employers.
