For a company trying to ward off unionization, firing a union activist is a great investment. While the National Labor Relations Act bans such retaliation, its process is slow and its penalties are minimal. Every time Democrats have controlled the presidency and Congress, unions have pushed reforms to the law—and every time they’ve come up short. In their new book, Why Labor Organizing Should Be a Civil Right, the Century Foundation’s Richard Kahlenberg and labor lawyer Moshe Marvit propose a new approach to labor law reform: add protection against anti-union discrimination to the Civil Rights Act. The Prospect talked to Kahlenberg about why he expects his proposal to succeed where others failed, the relationship between law and culture, and whether Ann Coulter has a point.
