Each week, In Theory takes on a big idea in the news and explores it from a range of perspectives. This week, we’re talking about paid family leave. Need a primer? Catch up here.

Isabel Sawhill is a senior fellow at the Brookings Institution. Her most recent book, “Generation Unbound: Drifting Into Sex and Parenthood Without Marriage,” is about changes in family life in the United States.

Throughout the past year, we have heard paid leave debated in statehouses and on the campaign trail. I am all in favor of paid leave. As I have argued elsewhere, it would enable more people — especially those in lower-paying jobs — to take time off to deal with a serious illness or the care of another family member, including a newborn child.

But we shouldn’t stop with paid leave. We should also consider shortening the standard workweek. Such a step would be gender-neutral and would not discriminate between the very different kinds of time pressures faced by adults. It might even help to create more jobs.

We need more than just paid leave. We need more parents.

The standard workweek is 40 hours — eight hours a day for five days a week. It’s been that way for a long time. Back in 1900, the typical factory worker spent 53 hours on the job, one-third more hours than we spend today. The Fair Labor Standards Act was passed in 1938 and set maximum hours at 40 per week. Amazingly, more than three-quarters of a century after passage of the FLSA, there has been no further decline in the standard workweek. Not only has the legal standard remained unchanged, but also 40 hours has become the social and cultural norm.

What’s going on here? Economists predicted that as we became more prosperous we would choose to work fewer hours. That hasn’t happened. Instead, we have kept on working at about the same pace as we did earlier in our history, pouring all of the gains from productivity growth into ever-higher levels of consumption: bigger houses, more electronic gadgets and fancier cars. With increased prosperity, people are buying more and more stuff, but they don’t have any more time to enjoy it. A reduction in the standard workweek would improve the quality of life, especially for those in hourly jobs who have benefited hardly at all from economic growth in recent decades.

Two-earner couples would also benefit. Among couples between ages 25 and 54, the number of hours worked increased by 20 percent between 1969 and 2000, from 56 hours to 67 hours (for both husband and wife combined). As Heather Boushey notes in her new book, “Finding Time,” we no longer live in a world where there is a “silent partner” in every business enterprise, the iconic “American Wife” who takes care of the children and the millions of details of daily living. With a shorter workweek, both men and women would have more time for everything from cutting the grass to cooking dinner with no presumption about who does what.

Although much of the debate this year has been about work-family balance, empty-nesters or singles without young children might also welcome a shorter workweek. For them, it would provide the chance to follow their dream of becoming an artist, a boat builder or the creator of their own small business.

Shorter hours could have another benefit: more jobs for workers who would otherwise be left behind by technological change. Many economists believe that as existing jobs are replaced by machines and artificial intelligence, new jobs will be created in technical, management and service fields. But will this happen fast enough or at sufficient scale to reemploy all those who now find themselves without decent-paying work? I doubt it.

A shorter workweek might help to spread the available jobs around. Germany and other European countries, along with a few U.S. states, used this strategy during the Great Recession. It kept more people on the job but at shorter hours and reduced unemployment. Using a similar strategy to deal with automation and long-term joblessness, although controversial, should not be dismissed out of hand.

Of course, shorter hours can mean lower total pay. But in one typical survey published in the Monthly Labor Review, 28 percent of the respondents said they would give up a day’s pay for one fewer day of work per week. Any new movement to reduce the work week would need to be phased in slowly, with flexibility for both employers and employees to negotiate adjustments around the standard. Yet if done correctly, the transition could be accomplished with little or no reduction in wages, just smaller raises as productivity improvement was invested in more free time. When Henry Ford reduced the workweek from six to five days in 1926, he did not cut wages. He assumed that both productivity and consumption would rise, and his example encouraged other employers to follow suit.

How a lack of paid leave is making wealth inequality worse

I am not talking about reducing hours for those of us who want to spend long hours at work because we enjoy it. We would still be free to work 24-7, tied to our electronic devices, and no longer knowing exactly when work begins and ends. A new hours standard would primarily affect hourly (nonexempt) employees. These are the people in the less glamorous jobs at the bottom of the ladder, many of them single parents. Right now they finish work exhausted only to come home to a “second shift” that may be equally exhausting. A reduction in the standard workweek would almost certainly improve the quality of life for these hard-pressed and overworked Americans.

By all means, let’s enact a paid leave policy, but let’s also debate some even bigger ideas — ones that could lead to greater work-life balance now, and more job opportunities in the longer run.
