She did. And so the manager talked about the sense of unfairness he felt as a supervisor, making enough to live comfortably while overseeing workers who couldn’t feed their families on the money they earned. That inequality, he told her, tainted his job, making him feel complicit in an unfair system that paid hard workers too little to cover basic needs.

The interview changed the way Dodson talked with other supervisors and managers of low-income workers, and she began to find that many of them felt the same discomfort as the grocery store manager. And many went a step further, finding ways to undermine the system and slip their workers extra money, food, or time needed to care for sick children. She was surprised how widespread these acts were. In her new book, “The Moral Underground: How Ordinary Americans Subvert an Unfair Economy,’’ she called such behavior “economic disobedience.’’

As Dodson’s questions grew more pointed, she began to hear fascinating stories. Andrew, a manager in a large Midwest food business, said he put extra money in the paychecks of those earning a “poverty wage,’’ punched out their time cards at the usual quitting time when they had to leave early for a doctor’s appointment, and gave them food.

Andrew had decided that by supervising workers who were treated unfairly - paid too little and subjected to inflexible schedules that prevented them from taking care of their families - he was playing a direct role in the unfair system, and so he was morally obligated to act.

Dodson concluded that Andrew and many like him were following the American tradition of civil disobedience - this time, against the economy - and creating a “moral underground.’’

But her book, which came out late last year, has provoked debate about the morality of such acts.

After Dodson talked about her book on a radio program, American Public Media’s “Marketplace,’’ some listeners posted comments on the show’s website arguing that supervisors like Andrew are cheating their employers.

Referring to the show’s host, a listener from Leesburg, Va., wrote, “I was surprised that throughout the entire interview, neither Tess Vigeland nor Ms. Dodson touched on what would seem to me a rather crucial point - that these ‘Ordinary Americans’ are stealing from the companies who employ them.

“The examples Ms. Dodson gave . . . are acts of theft from the companies, yet they are described as if somehow moral and virtuous. It’s one thing for me to see someone in need and open my wallet; its quite another to address that need by giving something I’ve stolen from my neighbor.’’Continued...
