When Simone Nelson was finally able to reach someone from the unemployment office in New York state on Tuesday, she was overjoyed.

Nelson, 22, had been making hundreds of calls a day, endlessly pressing redial after learning she no longer had a job at the bakery where she worked as a caterer and an events coordinator.

“I started with only 100 calls a day. And then on Saturday, I had three consecutive hours when I had two phones calling the unemployment office and it wasn’t working,” Nelson said. “It kept saying the reps were busy and hung up.”

Nelson is just one of the millions of Americans who are now part of the single largest mass-unemployment event ever recorded in the U.S. Two weeks ago, 3 million people applied for unemployment, a number that dwarfed any single week of jobless claims during past economic crises.

On Thursday, new data showed that an additional 6.6 million people applied for unemployment benefits last week.

Representatives for state unemployment offices across the country say the shock of such numbers has hit their workers almost as hard as the people calling after losing their jobs — and they describe the wrenching emotional toll the work is taking on call center staff, many of whom are still required to come into the office.

“The difference between the job loss of the 2008 recession and where we are now is we had more time to prepare then,” said Cher Haavind, the deputy executive director of the Colorado Department of Labor and Employment. “From a staff perspective, we just haven’t had time to really readjust in terms of both resources and support to staff, which includes this new role of our employees acting as mental health counselors.”

Labor and unemployment offices around the U.S. are adding staff, shoring up websites that have crashed from the high traffic, extending work hours, and calling in retired workers and opening on weekends to handle the influx of filings.

Unemployment workers are also facing personal risk.

Workers at the New York State Department of Labor’s call center for unemployment, most of whom are based in Binghamton, are still coming into the office, according to Wayne Spence, the president of the New York State Public Employees Federation, a union representing employees at the department.

Many of the people taking these calls are working 10-hour days, Spence said.

“Going into work at the unemployment office comes with a lot of fear, as they often work in tight locations and the idea of social distancing is pretty damn near impossible,” Spence said.

Unemployment office workers in many states are continuing to report to their desks, despite strict recommendations from the Centers for Disease Control and Prevention and state governments that people stay home and self-quarantine to slow the spread of the virus. These workers are considered essential employees — they’re manning the phone lines trying to help the millions of recently out of work across the country apply to receive unemployment checks to help support their families, buy food and pay bills, rent, and mortgages.

Unemployment office workers in Georgia are also coming into the office, according to Kersha Cartwright, the communications director at the state Department of Labor.

“We can’t work from home due to the number of claims that need to be processed and because we’re dealing with personal information, so we need to make sure our systems are secure,” Cartwright said.

“We are trying to get Georgians paid. They are scared. They are worried and they are anxious. We are doing whatever we can,” she said, adding that at their office employees have distanced their desks and aren’t doing meetings in the same room anymore, but rather video conferencing even though everyone is in the same office.

The New Jersey Department of Labor said in an email that it has been practicing social distancing at its office, too. In Florida, employees at the state’s Department of Economic Opportunity are also coming into the office and trying to keep their distance.

“Yes, our team is coming into the office,” said Tiffany Vause, the communications director at Florida’s Department of Economic Opportunity. “I’ve got two kids at home that my husband and I are trying to educate and juggle work and everything else. Our staff who are taking calls, they’ve got kids at home, too.”

Many offices are reporting dramatic increases in unemployment claims.

In a press release last week, the New York state Department of Labor said that the number of claims processed rose by more than 500 percent compared to the year before, which doesn’t account for the calls that haven’t gotten through.

In California, Gov. Gavin Newsom said this week that 1.6 million people have so far applied for unemployment insurance since businesses started to close last month in response to the coronavirus. California usually averages about 2,000 claims a day, but on Monday more than 150,000 people filed for uninsurance, Newsom said.

It’s a similar story across the country. In Colorado in the last week, the Department of Labor doubled its call center staff to handle the massive increase in call volume.

Washington state, hit hard early in the outbreak in the U.S., reported a 1,000 percent increase in its usual call volume, at times receiving more than 20,000 calls a day.

Florida’s Department of Economic Opportunity received 222,054 applications for assistance last week, a spokesperson said in an email.

The Texas Workforce Commission said last week it received up to 1.5 million calls in a single day.

The wave of unemployment claims is forcing offices to find ways to add staff members.

In Georgia, the Department of Labor has been calling recently retired workers to come back to help, and Florida has turned to an outside staffing agency to hire 250 workers to help handle the increase in calls.

Some state unemployment center workers are able to work from home, like in Colorado and Washington, thanks to agency-issued laptops and software that allows employees to take calls over the internet.

Washington state is hiring hundreds of workers to help people process claims. The state’s unemployment agency conducted about 140 phone interviews last week, said Nick Demerice, the director of external affairs at the state’s Employment Security Department.

“We definitely want to approach those conversations with a high degree of compassion and empathy,” Demerice said. “Unlike other natural disasters that put people out of work, this isn’t just one area of the state. This is affecting all of us.”
