It looks like something to celebrate: small businesses posting “Help Wanted” signs as the economy edges toward normalcy. Instead, businesses are having trouble filling the jobs, which in turn hurts their ability to keep up with the demand for their products or services.

Owners say that some would-be workers are worried about catching COVID-19 or prefer to live off unemployment benefits that are significantly higher amid the pandemic. Child care is another issue — parents aren’t able to work when they need to tend to or home-school their children. For some people, a combination of factors goes into their decision not to seek work.

When Steve Klatt and Brandon Lapp set up interviews for their restaurant and food truck business, they’re lucky if one out of 10 or 15 applicants comes in.

“The people who do show up, all assume their unemployment is running out,” says Klatt, whose business, Braised in the South, is located in Johns Island, South Carolina. The maximum weekly unemployment benefits in the state are $626 including $300 in federal coronavirus relief payments; in some states, maximum unemployment is over $700 a week.

Klatt and Lapp need 20 people to run the business well but have only five staffers. Former chefs, the owners, and their wives are working in the kitchen and on the truck to keep things running. Klatt and Lapp recently decided to curtail their Sunday hours and close Mondays to give everyone a break.

“The hit to the bottom line will be noticeable, but it’s not worth burning out the few awesome people we do have to work for us,” Klatt says.

Businesses of all sizes are struggling with hiring even with millions of Americans unemployed and as increasing numbers of people get vaccinated and look forward to a more normal life. A Census survey taken in late March shows that 6.3 million didn’t seek work because they had to care for a child, and 4.1 million said they feared contracting or spreading the virus.

But smaller companies that often can’t offer pay and benefits as generous as larger companies have a tougher time.

“A shortage of talent is nothing new for small businesses, but the circumstances surrounding this shortage are entirely different,” says Jill Chapman, a consultant with Insperity, a human resources provider.

The National Federation of Independent Business found in a March survey of its own members that 42% had job openings they couldn’t fill. Owners cited higher unemployment benefits as one factor. And a study released last month by the National Bureau of Economic Research found that a 10% increase in unemployment benefits during the pandemic led to a 3.6% drop in job applications.

“Unemployment benefits allow workers to be able to wait longer before they take a job, which can make hiring harder,” said Ioana Marinescu, a University of Pennsylvania professor who co-authored the study.

Companies whose work is done inside homes — including plumbers, contractors, and pest control businesses — find many prospective hires are afraid of contracting the virus on a job. Meanwhile, demand for their services is up because there’s more wear and tear on houses and apartments as people spend more time at home.

At Jake Romano’s Ottawa, Ontario, plumbing business, job candidates are gravitating toward commercial plumbing rather than having to visit five to 10 homes a day. Even when Romano finds a good prospect for his company, John the Plumber, he’s often disappointed.

“We had a really good applicant, who I found on Facebook. He agreed to come on board, everything was looking good. I was excited, he was excited. Then, bam! He changed his mind,” says Romano, who’s looking for two licensed plumbers to add to his current staff of 10.

Economist Joe Brusuelas says child care is another issue that may extend owners’ struggles to find workers.

“Until the schools are reopened and avenues of child care normalized, small firms in general, as well as food, beverage, leisure, and hospitality, in particular, are going to face staffing challenges until later this fall at the earliest,” says Brusuelas, chief economist with the consulting firm RSM.

Jillian Melton was laid off from a Seasons 52 restaurant in Memphis, Tennessee, last spring when the pandemic shut the restaurant down. Melton, who had worked at the restaurant for seven years, can’t work a regular schedule; she has three children at home from school and she’s caring for her 93-year-old grandmother. Babysitters and nurses are in short supply.

Melton says employers need to understand that many workers have compromised immune systems or limited availability because schools and daycare centers are closed. Some people, upended by the pandemic, are just looking for new lines of work, she says.

“All of it is just a hot mess,” she says.

Child care is one reason why the pool of available workers has shrunk dramatically at Let Mommy Sleep, which hires nurses and health aides to provide in-home care for babies and give new mothers a respite. Founder Denise Stern says some of her caregivers want to work overnight and sleep during the day, but if they have their own children to care for, that’s not possible.

Stern also is being hamstrung by concerns about the virus.

“We can’t hire candidates with second jobs where exposure might happen, and honestly, a lot of candidates don’t want to work in a closed environment where we know transmission happens,” Stern says.

Stern has had to turn business away, and so have the owners of seven Let Mommy Sleep franchises around the country. Stern, who works in the Washington, D.C., area, says her revenue is down by half.

Revenue is down 30% at Filter King, based in Miami. Demand for air filters is jumping as people work from home and run their air conditioners more, but owners Mike Jacob and Rick Hoskins need to double their staff of 20 to keep up with orders.

“The unemployment benefits continue and it’s hard to get people off the couch and into the warehouse,” Jacob says.

But even when people are willing to work, Filter King is at a disadvantage compared to companies that can pay more, Jacob says. He’s lost staffers and candidates to a competitor funded by a venture capital firm.

Stonehedge Farms, a popcorn manufacturer in Dover, Pennsylvania, raised its hourly pay to $13.50 from $12 in hopes of attracting more workers but co-owners Shannon and Anthony Tsonis haven’t been able to find enough people to fill the factory’s two shifts. They have 30 staffers and need another 10; the Tsonises and their office staffers have to fill in at the factory.

Before the pandemic, Tsonis could rely on one of three applicants showing for interviews. Now, it’s more likely to be one in 10.

“This would lead me to believe they are simply applying to meet the (job search) requirements of unemployment, which is frustrating. It’s frustrating because we need people, and it’s frustrating because it’s a waste of our time and resources for recruitment,” Tsonis says.

Seven Sisters Scones, a bakery, and cafe in Johns Creek, Georgia, has struggled to find staffers not only because of unemployment benefits but because parents need to be home with their children, co-owner Hala Haider says. The shop has 15 staffers and needs four more.

Because of the shortfall, Seven Sisters Scones can’t make deliveries and they’ll be selling at fewer farmers’ markets than usual this summer. And Haider and her co-owner, her sister Farrah, have had to turn down some new business. But they draw the line at scaling back their online business, which allows them to reach customers across the country.

“That is one thing we don’t compromise on — it’s a priority,” Hala Haider says.

As the United States surpassed 200 million administered coronavirus vaccine doses, President Joe Biden on Wednesday said businesses will be incentivized for encouraging employees and making it easier for them to get vaccinated.

The Biden administration will focus on increased outreach in the coming weeks, hoping to connect with Americans who have yet to receive a vaccine.

This also means addressing obstacles that keep them from getting vaccinated.

"Vaccines can save your own life, but they can also save your grandmother's life, your co-worker's life, the grocery store clerk or the delivery person helping you and your neighbors get through the crisis," Biden said, according to a report by The Associated Press. "That's why you should get vaccinated."

Here are five key takeaways from Biden's remarks:

1. Biden said a tax credit will be given to small businesses that provide paid leave for employees to get vaccinated and to recover from potential side effects. The change would provide a credit of up to $511 per day per employee for businesses with 500 or fewer employees, The AP reported. The change would be paid for through the $1.9 trillion virus relief package passed last month.

2. Large employers were also encouraged to provide paid leave benefits to employees wishing to get vaccinated.

3. Every person 16 years or older are now eligible to receive the coronavirus vaccine, Biden said. He also noted that 90 percent of Americans live within five miles of a place administering vaccines they can get vaccinated, according to a report by The Hill.

4. More than 80 percent of people 65 years or older have received the vaccine, according to a report by The Hill.

5. Biden encouraged Americans to continue to mask up and socially distance, noting the country is still on track to have safe gatherings by the Fourth of July.

More than 50 percent of U.S. adults have received at least one dose of the vaccine, and roughly 28 million doses are being delivered each week, according to The AP.

Yet Biden's remarks come as the United States approaches a turning point — one where vaccine supply may be on track to outpace demand.

Iowa is one example. Nearly half of all counties there are no longer accepting new doses of the COVID-19 vaccine because demand has decreased, The AP reported. In Florida, Palm Beach County plans to close mass vaccination clinics at the end of May with thousands of available vaccine slots unclaimed. In Arizona, a plan to open a federally run vaccine site in Tucson also fell through due to slipping demand.

At the same time, most Americans who haven't been immunized say they're unlikely to get the shots, according to a recent poll by The Washington Post.

While incentives may be enough to prompt employers to encourage employees to get vaccinated, many could still opt to require them.

Whether an employer can mandate vaccines varies by state, according to guidance from the Centers for Disease Control and Prevention.

From a legal standpoint, however, employers are allowed to ask their employees whether they have been vaccinated. They can also request proof of vaccination, according to a Washington Post report citing recent guidance from the U.S. Equal Employment Opportunity Commission, which enforces federal nondiscrimination laws in the workplace.
