How do they say economic recovery? 'I quit.'

At some point early this year, Justin Hoffman concluded that he was being underpaid.

The marketing director at an orthopedic practice in Findlay, Ohio, Hoffman was making $42,000 a year — about $13,000 less, by his count, than people were making in similar jobs elsewhere.

But when he asked for a raise in March, he was given only a small bump in pay.

"That was kind of the straw that broke the camel's back," he said.

So after some careful thinking, Hoffman, 28, did what he had long ached to do: He quit. His last day was June 4.

Hoffman is among millions of workers who have voluntarily left their jobs recently, one of the most striking elements of the newly blazing-hot job market. According to the Labor Department, nearly 4 million people quit their jobs in April, the most on record, pushing the rate to 2.7% of those employed.

The rate was particularly high in the leisure and hospitality industry, where competition for workers has been especially fierce. But the number of those quitting registered across the board.

But another factor may be the speed with which the economy has reawakened. As the pandemic has receded and the great reopening has swept the country, businesses that had gone into hibernation or curtailed their workforce during the pandemic have raced to hire employees to meet the surging demand.

At the same time, many people remain reluctant to return to work because of lingering fears of the virus, child care or elder care challenges, still-generous unemployment benefits, low wages or other reasons.

The result has been an explosion of job openings, despite a relatively high unemployment rate, as businesses struggle to recruit and retain employees — a dynamic that has placed power more firmly in workers' hands. With employers offering higher wages to attract candidates, many workers — especially in low-wage positions in restaurants and hotels — are leaving their jobs and jumping to ones that pay even slightly more.

The pandemic has driven workers to quit for other reasons as well. With fewer opportunities for spending, some people were able to save money and pay down their debts, giving them a cushion to leave jobs with which they were dissatisfied. Other workers, disinclined to give up remote work, are abandoning jobs that are no longer affording them as much flexibility.

For Hoffman, the decision to leave his job was the culmination of months of perceived injustices, which he said he was able to evaluate more clearly because of the pandemic.

Over the past year, with the pandemic limiting his social interactions, he began to network over Twitter with other people in marketing. That was how he determined that he was being significantly underpaid.

Hoffman, who is now looking for work, said he probably would have quit eventually. But the pandemic, he said, hastened his decision.

"I think that if the pandemic hadn't happened, then things wouldn't have turned out this way," he said. "It didn't just change my perspective on my compensation, but I think it's changed a lot about my understanding of the relationship between employers and employees."

On a more philosophical level, the constant threat of illness, more time with family members, leisure time that gave way to new passions — all may have prompted some workers to reassess how they want to spend their time. Burned out, some people have left their jobs for once-in-a-lifetime experiences, like traveling the world. Others have seen an opportunity to shift careers or branch out on their own.

Startups surged during the pandemic, particularly in Black communities, as stimulus checks and unemployment benefits helped seed entrepreneurs' dreams and bolster their confidence.

Klotz said people were accustomed to work being at the center of their lives and identities — a reality that may have shifted during the pandemic.
