Despite school reopenings and the end of some federal aid, many people are in no rush to land a job. Savings and health concerns are playing a role.Fall was meant to mark the beginning of the end of the labor shortage that has held back the nation’s economic recovery. Expanded unemployment benefits were ending. Schools were reopening, freeing up many caregivers. Surely, economists and business owners reasoned, a flood of workers would follow.Instead, the labor force shrank in September. There are five million fewer people working than before the pandemic began, and three million fewer even looking for work.The slow return of workers is causing headaches for the Biden administration, which was counting on a strong economic rebound to give momentum to its political agenda. Forecasters were largely blindsided by the problem and don’t know how long it will last.Conservatives have blamed generous unemployment benefits for keeping people at home, but evidence from states that ended the payments early suggests that any impact was small. Progressives say companies could find workers if they paid more, but the shortages aren’t limited to low-wage industries.Instead, economists point to a complex, overlapping web of factors, many of which could be slow to reverse.The health crisis is still making it hard or dangerous for some people to work, while savings built up during the pandemic have made it easier for others to turn down jobs they do not want. Psychology may also play a role: Surveys suggest that the pandemic led many to rethink their priorities, while the glut of open jobs — more than 10 million in August — may be motivating some to hold out for a better offer.The net result is that, arguably for the first time in decades, workers up and down the income ladder have leverage. And they are using it to demand not just higher pay but also flexible hours, more generous benefits and better working conditions. A record 4.3 million people quit their jobs in August, in some cases midshift to take a better-paying position down the street.“It’s like the whole country is in some kind of union renegotiation,” said Betsey Stevenson, a University of Michigan economist who was an adviser to President Barack Obama. “I don’t know who’s going to win in this bargaining that’s going on right now, but right now it seems like workers have the upper hand.”The slow return of workers is causing headaches for the Biden administration, which was counting on a strong economic rebound to give momentum to its political agenda.Kendrick Brinson for The New York TimesRachel Eager spent last fall at home, taking the last class for her bachelor’s degree over Zoom while waiting to be recalled to her job at a New York City after-school program. That call never came.So Ms. Eager, 25, is looking for work. She has applied for dozens of jobs and had a handful of interviews, so far without luck. But she is taking her time. Ms. Eager says she is still worried about catching Covid-19 — she would prefer to work remotely, and if she does end up taking an in-person job, she wants it to be worth the risk. And she doesn’t want another job with low pay, little flexibility and no benefits.“Many, many people are realizing that the way things were prepandemic were not sustainable and not benefiting them,” she said. She has been applying for jobs in data analysis, nonprofit management and other fields that would offer better pay, benefits and a sense of purpose.Ms. Eager, who is vaccinated, said that she had always been careful with money and that she built savings this year by staying home and socking away unemployment benefits and other aid. “My financial situation is OK, and I think that is 99 percent of the reason that I can be choosy about my job prospects,” she said.Americans have saved trillions of dollars since the pandemic began. Much of that wealth is concentrated among high earners, who mostly kept their jobs, reduced spending on dining and vacations, and benefited from a soaring stock market. But many lower-income Americans, too, were able to set aside money thanks to the government’s multitrillion-dollar response to the pandemic, which included not only direct cash assistance but also increased food aid, forbearance on mortgages and student loans and an eviction moratorium. Economists said the extra savings alone aren’t necessarily keeping people out of the labor force. But the cushion is letting people be more picky about the jobs they take, when many have good reasons to be picky.In addition to health concerns, child care issues remain a factor. Most schools have resumed in-person classes, but parents in many districts have had to grapple with quarantines or temporary returns to remote learning. And many parents of younger children are struggling to find day care, in part because that industry is dealing with its own staffing crisis.Liz Kelly-Campanale left her job as a winemaker last year to care for her two children in Portland, Ore. She thought about going back to work when schools resumed in-person instruction this fall. But the Delta variant upended those plans.“If you have an exposure, all of a sudden your kids are out of school for 10 days,” she said. “For people who have jobs where they can work from home, it’s maybe a little more feasible, but I can’t really drive a forklift around the house.”Ms. Kelly-Campanale, 37, said she might go back to work once her children, now 6 and 3, are vaccinated and the pandemic seems under control. But she said the pandemic has led her to rethink her priorities.“So much of how I saw myself was tied up in what I did for a living — it was a huge adjustment to all of a sudden not be doing that all the time,” she said. “But once I made that adjustment, it also became apparent that there were also benefits to having that work-life balance.”Economists worry that if the pandemic leads many people to opt out of the work force, it could have long-term consequences for economic growth. Rising labor force participation, particularly among women, was a major driver of the strong gains in income and production after World War II. Many economists argue that the reversal of that trend in recent decades has hurt economic growth..css-1xzcza9{list-style-type:disc;padding-inline-start:1em;}.css-3btd0c{font-family:nyt-franklin,helvetica,arial,sans-serif;font-size:1rem;line-height:1.375rem;color:#333;margin-bottom:0.78125rem;}@media (min-width:740px){.css-3btd0c{font-size:1.0625rem;line-height:1.5rem;margin-bottom:0.9375rem;}}.css-3btd0c strong{font-weight:600;}.css-3btd0c em{font-style:italic;}.css-1kpebx{margin:0 auto;font-family:nyt-franklin,helvetica,arial,sans-serif;font-weight:700;font-size:1.125rem;line-height:1.3125rem;color:#121212;}#NYT_BELOW_MAIN_CONTENT_REGION .css-1kpebx{font-family:nyt-cheltenham,georgia,’times new roman’,times,serif;font-weight:700;font-size:1.375rem;line-height:1.625rem;}@media (min-width:740px){#NYT_BELOW_MAIN_CONTENT_REGION .css-1kpebx{font-size:1.6875rem;line-height:1.875rem;}}@media (min-width:740px){.css-1kpebx{font-size:1.25rem;line-height:1.4375rem;}}.css-1gtxqqv{margin-bottom:0;}.css-1g3vlj0{font-family:nyt-franklin,helvetica,arial,sans-serif;font-size:1rem;line-height:1.375rem;color:#333;margin-bottom:0.78125rem;}@media (min-width:740px){.css-1g3vlj0{font-size:1.0625rem;line-height:1.5rem;margin-bottom:0.9375rem;}}.css-1g3vlj0 strong{font-weight:600;}.css-1g3vlj0 em{font-style:italic;}.css-1g3vlj0{margin-bottom:0;margin-top:0.25rem;}.css-19zsuqr{display:block;margin-bottom:0.9375rem;}.css-12vbvwq{background-color:white;border:1px solid #e2e2e2;width:calc(100% – 40px);max-width:600px;margin:1.5rem auto 1.9rem;padding:15px;box-sizing:border-box;}@media (min-width:740px){.css-12vbvwq{padding:20px;width:100%;}}.css-12vbvwq:focus{outline:1px solid #e2e2e2;}#NYT_BELOW_MAIN_CONTENT_REGION .css-12vbvwq{border:none;padding:10px 0 0;border-top:2px solid #121212;}.css-12vbvwq[data-truncated] .css-rdoyk0{-webkit-transform:rotate(0deg);-ms-transform:rotate(0deg);transform:rotate(0deg);}.css-12vbvwq[data-truncated] .css-eb027h{max-height:300px;overflow:hidden;-webkit-transition:none;transition:none;}.css-12vbvwq[data-truncated] .css-5gimkt:after{content:’See more’;}.css-12vbvwq[data-truncated] .css-6mllg9{opacity:1;}.css-qjk116{margin:0 auto;overflow:hidden;}.css-qjk116 strong{font-weight:700;}.css-qjk116 em{font-style:italic;}.css-qjk116 a{color:#326891;-webkit-text-decoration:underline;text-decoration:underline;text-underline-offset:1px;-webkit-text-decoration-thickness:1px;text-decoration-thickness:1px;-webkit-text-decoration-color:#326891;text-decoration-color:#326891;}.css-qjk116 a:visited{color:#326891;-webkit-text-decoration-color:#326891;text-decoration-color:#326891;}.css-qjk116 a:hover{-webkit-text-decoration:none;text-decoration:none;}In the shorter term, many economists think that more people will return to work as pandemic-related issues recede and as people deplete their savings.“Eventually those savings, especially for lower-income people, they’re going to run out,” said Pablo Villanueva, an economist at UBS. “A lot of people are going to be increasingly unable to stay out of work even if they have some fear of Covid.”Some businesses seem determined to wait them out. Wages have risen, but many employers appear reluctant to make other changes to attract workers, like flexible schedules and better benefits. That may be partly because, for all their complaints about a labor shortage, many companies are finding that they can get by with fewer workers, in some instances by asking customers to accept long waits or reduced service.“They’re making a lot of profits in part because they’re saving on labor costs, and the question is how long can that go on,” said Julia Pollak, chief economist for the employment site ZipRecruiter. Eventually, she said, customers may get tired of busing their own tables or sitting on hold for hours, and employers may be forced to give into workers’ demands.Some businesses are already changing how they operate. When Karter Louis opened his latest restaurant this year, he abandoned the industry-standard approach to staffing, with kitchen workers earning low wages and waiters relying on tips. At Soul Slice, his soul-food pizza restaurant in Oakland, Calif., everyone works full time, earns a salary rather than an hourly wage, and receives health insurance, retirement benefits and paid vacation. Hiring still hasn’t been easy, he said, but he isn’t having the staffing problems that other restaurants report.Restaurant owners wondering why they can’t find workers, Mr. Louis said, need to look at the way they treated workers before the pandemic, and also during it, when the industry laid off millions.“The restaurant industry didn’t really have the back of its people,” he said.Still, better pay and benefits alone won’t bring back everyone who has left the job market. The steepest drop in labor force participation came among older workers, who faced the greatest risks from the virus. Some may return to work as the health situation improves, but others have simply retired.And even some nowhere near retirement have made ends meet outside a traditional job.When Danielle Miess, 30, lost her job at a Philadelphia-area travel agency at the start of the pandemic, it was in some ways a blessing. Some time away helped her realize how bad the job had been for her mental health, and for her finances — her bank balance was negative on the day she was laid off. With federally supplemented unemployment benefits providing more than she made on the job, she said, she gained a measure of financial stability.Ms. Miess’s unemployment benefits ran out in September, but she isn’t looking for another office job. Instead, she is cobbling together a living from a variety of gigs. She is trying to build a business as an independent travel agent, while also doing house sitting, dog sitting and selling clothes online. She estimates she is earning somewhat more than the roughly $36,000 a year she made before the pandemic, and although she is working as many hours as ever, she enjoys the flexibility.“The thought of going to an office job 40 hours a week and clocking in at the exact time, it sounds incredibly difficult,” she said. “The rigidity of doing that job, feeling like I’m being watched like a hawk, it just doesn’t sound fun. I really don’t want to go back to that.” More
