There’s a widely held belief that Americans are less loyal to employers than they were in prior eras. And with pensions virtually extinct and job security close to nil, who can blame them. But the truth is employees stick with the same job longer today than they did 10, 20, and 30 years ago—and economists say that may not be a good thing.

U.S. workers have been in their current job for a median of 4.2 years in January 2016—that’s up from 3.7 years in 2002 and 3.5 in 1983, according to the Bureau of Labor Statistics. People’s relationship with work changes dramatically from when they are 16 to, say, 46, and this trend rises with age for both sexes—5.1 years in January 2016 for those aged 25 years, 7.9 years for those aged 45 to 54 and over 10 years for those 55 years and over.

American workers are stuck in a rut, economists say. Despite improvements in education and technology, they’re staying in their jobs longer rather than seeking new opportunities. A high “churn” rate is typically seen as a reflection of a healthy economy. “People are holding on to their jobs not because they want to, but because they don’t have as much opportunity as they once did,” says Anthony Carnevale, director of the Georgetown University Center on Education and the Workforce.

American workers are also not sticking with their jobs out of mere convenience—certainly not when it comes to their commutes, studies suggest. Although 54% of workers say they like the people they work with, only 29% feel valued in their jobs and just 35% say they have a fast commute, according to a new survey by jobs listing website CareerBuilder.com and research firm Harris Interactive.

More workers want to get out: 21% of full-time employees want to change jobs in 2014, the largest percentage since 2008 and up from 17% in 2013, the study of over 3,000 workers found. “During the recession and in its aftermath fewer people voluntarily left jobs because the chances of finding a new or better one were low compared to a healthier economic cycle,” says Rosemary Haefner, vice president of human resources for CareerBuilder.

Older workers are staying in employment longer than any other age group. Over half of workers age 55 to 64 and those age 65 and over had 10 years or more of tenure, compared with fewer than 10% of workers in their 20s and 30s, according to the Bureau of Labor Statistics data. Older people in the workforce are less reluctant—or able—to retire since the Great Recession, experts say. “Older people are hanging on in the workforce longer,” says Steven F. Hipple, economist at the U.S. Bureau of Labor Statistics.

“Younger people have been hurt most by this,” Carnevale says. It now takes the average worker until age 30 to earn the national median salary; young workers in 1980 reached that point in their careers at age 26, according to a 2013 Georgetown University study, “Failure to Launch: Structural Shift and the New Lost Generation.”

Young men have been hardest hit: As their access to blue-collar occupations has declined over the past three decades, they’ve been left unable to find work or are increasingly likely to work in jobs that pay less. In 1980, young men earned 85% of the average wage in the labor market; today, they earn only 58%, Carnevale says.

Of course, there has been some recovery in the labor market in recent years. There were about 3.4% so-called separations (as measured as a percentage of total employment) in December 2016; this is still down from 3.6% a year earlier.

Still, a 25% churn rate is still considered a dynamic jobs market by international standards, he says, especially as it’s closer to 10% in many European countries where staying in the same job is often regarded as a positive choice. Carnevale expects 30 million job opportunities created by retiring boomers over the next 10 years, starting sometime after 2016—good news for the next U.S. President. “Whoever comes next will be able to do all the happy talk,” he says.
