Editor's note

With union membership hovering at about 11 percent of the national workforce, Labor Day might seem to be more of a celebration of grilling than collective bargaining. But, research by Thomas Kochan – a professor of work and employment relations – and his colleagues suggest that nearly half U.S. of workers would join a union if they could.

You know who can’t join unions? Prisoners. According to Arizona State University historian Calvin Schermerhorn, people imprisoned in the U.S. often produce our food, fight wildfires and make our sugar, all for a few cents per hour. The number of industries that use incarcerated Americans for labor may surprise you.

Labor Day is often regarded as a day off. But a psychologist, an anthropologist and an historian who teach at an engineering college believe it is an ideal time for college educators to reflect on ways to inspire students from different disciplines to collaborate to tackle some of the world’s most complex challenges.

Future of work

  • Is freelancing the future of employment?

    Freelancing is hardly the glamorous, coffee-fueled industry shown on TV. In OECD countries, most gig workers are in the service sector.

    People will still be needed on factory floors, even as robots become more common. Future operators will have technical support and be super-strong, super-smart and constantly connected.

    Today, the U.S. is leading the robotics revolution. But without timely investment, China will overtake us, and could permanently put Americans out of work.
