In March, US lawmakers approved more than $2.4tn (£1.7tn) in economic relief for businesses and households, in an attempt to blunt the economic distress as the pandemic threw more than 20 million people out of work and unemployment rates spiked to nearly 15%.
But support has been dwindling since the summer and several key programmes - including benefits for jobless gig workers and people out of work for more than six months - are due to expire at the end of December.
"For Congress to allow this many workers to be cut off … it's unprecedented," says Andrew Stettner, a senior fellow at The Century Foundation, a progressive think tank that estimated recently that more than 4 million people had already lost benefits and another 12 million could be cut off by the end of the year.
Without action, "the short-term impact is going to be more economic deprivation," says James Sullivan, economics professor at the University of Notre Dame, whose research has found that roughly 7 million people have fallen into poverty since May, many of them African American, children and those without university degrees.
After the 2007-8 financial crisis, Congress took steps to make it possible to collect nearly two years of unemployment benefits.
"It's frustrating because a lot of the people in Washington aren't hurting like we are so they don't understand how important it is for people who need it," she says.
This week, with the end-of-December deadline looming, stimulus talks have appeared to revive, with discussion of a compromise bill - which got a nod of support from president-elect Joe Biden - that would extend unemployment assistance until the end of March, among other relief.
"I do think we are seeing them wake up," says Mr Stettner.
Aside from unemployment, Democrats want money for state and local governments, while Republicans say legal protections for businesses from Covid-related worker lawsuits are essential.
Even if lawmakers agree on a compromise, Mr Stettner says the measures under discussions are only enough to be considered stop-gap solutions.
"For me personally, it is something that I have not seen before," says 32-year-old Stephanie Freed, a New York-based production electrician and lighting designer for live entertainment who has been out of work since late February and started an organization to lobby Congress on the issue this summer.
Derrick Cisneros, who worked as a behavioural therapist in California until March, says he is struggling to make it on the $300 unemployment cheque he receives every two weeks, forcing him to lean on his roommate and family for assistance.
"I'm late on some payments and I hate asking people for money so I try to save every penny that I get," the 35-year-old says?
