We’ve been told for decades that retirement is the finish line. Work hard, save up, and one day you get to stop. No more alarm clocks, no more meetings, no more deadlines. Sounds perfect, right? Yet something remarkable is happening across America right now. Retirees, in growing numbers, are quietly heading back into the workforce. And the story behind it is far more complex, far more human, and honestly far more surprising than most people think.
The easy assumption is that boredom sends older adults back to their desks or shop floors. It makes a tidy narrative. But when you actually dig into the data from 2024 and 2025, boredom turns out to be just one small thread in a much larger puzzle. Financial pressures, identity crises, healthcare costs, loneliness, and a shifting economy are all interlocking at once. Let’s dive in.
Here Are the 10 Key Reasons Driving This Remarkable Trend
The “unretirement” wave is no longer a fringe phenomenon. It’s a measurable, data-backed trend reshaping the American workforce. Researchers, financial planners, and labor economists have all started paying serious attention to it, and what they’re finding challenges nearly every assumption we’ve ever held about life after work.
Here are the 10 key reasons driving this remarkable trend, and honestly, some of them might genuinely surprise you. Each one reveals a different layer of why retirement, for millions of Americans, is no longer quite what it used to be.
1. The Cost of Living Has Simply Outpaced What Retirees Planned For
Let’s be real: nobody budgets perfectly for a retirement that spans two or three decades. Inflation, in particular, has blindsided a generation of retirees who carefully calculated their savings years ago, only to watch everyday costs surge well past what they anticipated.
The top reason for returning to work is inflation and increased cost of living. In May 2024, Indeed Flex surveyed 1,000 adults between the ages of 62 and 85, and one out of every five respondents reported they had returned to work due to rising expenses.
Millions of Americans are entering retirement while living costs remain high, life expectancy continues to rise, and fixed incomes feel less forgiving than they once did. For many households, fully stepping away from work no longer feels guaranteed.
For 2025, the cost-of-living adjustment on Social Security was just 2.5%, according to the Social Security Administration. That structure helps explain why retirees can feel squeezed even when benefits rise. Costs often move first. Adjustments arrive later. It’s a bit like trying to fill a bathtub with the drain half open. You’re adding water, but never quite catching up.
2. Retirement Savings Were Never Enough to Begin With
Here’s the thing that rarely makes headlines: a startling number of Americans arrive at retirement age without nearly enough saved. The shift away from pension-style plans over the past few decades has quietly placed an enormous burden on individual workers.
In the last few decades, employers have moved away from offering pension-style retirement plans in favor of defined contribution plans like 401k and 403b programs. This means workers carry more responsibility to save for retirement throughout their working years, and those who haven’t saved enough may need to keep working or return to work once they’ve retired.
More than half of respondents in a 2024 CNBC and SurveyMonkey poll said they are behind on retirement planning and savings. Among seniors who returned to work, insufficient retirement savings was cited as a top reason by a significant share, alongside the cost of living increasing more than expected.
The U.S. Bank 2025 Wealth Report adds another dimension: nearly two-thirds of all Americans worry they may eventually have to re-enter the workforce after retiring, while only 58% believe their money will actually last through retirement. That gap between expectation and reality is pushing more people to plan for, or stumble into, unretirement as a practical necessity.
3. Loneliness and the Loss of Social Connection Hit Harder Than Expected
Think about it this way: if you spent 40 years surrounded by colleagues, deadlines, and daily conversations, then suddenly found yourself with a completely empty calendar, the silence would hit like a wall. For many retirees, that’s exactly what happens.
Boredom is understandable, especially for those who went from working 40 hours per week to not working at all. For the same reason, it’s not surprising that loneliness was the reason that nearly half of retirees surveyed are considering working again.
The reasons retirees return to work vary along gender and marital lines. Research found that women and single retirees are more likely to cite income as the primary motivator for working into retirement, while men were more likely to cite social connections as a motivator to return to work.
About 15% of unretirees said boredom drove them back, and 14% said they simply want to stay active, mentally engaged, and socially connected. For these workers, retirement felt less like freedom and more like isolation. That’s a profound thing to admit, and it deserves far more attention in the conversation about retirement planning.
4. The Search for Purpose and Identity After Leaving a Career
Work, for many people, is not just a paycheck. It’s an identity. It’s how they answer the question “What do you do?” at every dinner party, family gathering, and chance meeting. When that identity disappears overnight, the psychological impact can be genuinely destabilizing.
Survey data indicated that retirees who are working full time are most often motivated by the desire for mental stimulation and professional fulfillment that they find in their work. They may especially appreciate the opportunity to work on their own terms, rather than out of sheer necessity.
Today, there is no set retirement age for those who wish to continue working or re-enter the workforce. Many seniors are choosing to remain employed not just for financial reasons, but because they still feel a strong desire to contribute in meaningful ways, often exploring new career paths or passions they never had the chance to pursue earlier in life.
I think this is one of the most underappreciated factors in the entire conversation. When someone has built a career over 30 or 40 years, retiring without a clearly defined new purpose is not a vacation. It can feel like an identity vacuum. Returning to work, even part-time, often fills that vacuum in ways that no amount of golf or gardening quite manages to.
5. Rising Healthcare Costs Are Forcing Retirees Back Into Employment
Healthcare is the silent budget-destroyer of retirement. It’s not talked about enough. People plan carefully for their housing, travel, and daily expenses, then discover that medical costs in later years are an entirely different beast.
Many reasons given for returning to work were tied to not having enough savings, including inflation concerns, the need for health insurance, stock market volatility, and the fear of outliving one’s savings.
An older worker losing their job unexpectedly often ends up experiencing long periods without health insurance. They also face greater difficulty accessing health care if they’re under 65 and not yet eligible for Medicare. For retirees who left work before 65, the gap in coverage can be enormous and expensive.
If enrolled in Medicare, higher income could result in an income-related monthly adjustment amount surcharge on Medicare premiums. Still, for some retirees, gaining employer-sponsored health insurance by returning to work actually makes financial sense, even when the numbers seem counterintuitive at first glance.
6. The “Unretirement” Surge Is Accelerating at a Measurable Rate
This isn’t a slow trickle. The numbers behind the unretirement trend are growing year over year, and labor market data confirms it clearly. In 2024, about nearly one in five people age 65 and older were in the labor force, according to the U.S. Bureau of Labor Statistics, up from about 12.9% in 2000.
According to a February 2026 survey by AARP, 7% of retirees have returned to work in the past six months, up from 6% who said the same in summer 2025. Indeed Flex also reported its usage among people age 62 and older had grown 70 percent compared with January 2024.
According to Pew Research, individuals age 75 and older are the fastest growing age group in the workforce. In fact, this worker demographic has more than quadrupled in size since 1964. A survey conducted by ResumeBuilder found similar results, with one in eight retirees between the ages of 65 and 85 reporting that they’re likely to return to the workforce in 2025.
The Bureau of Labor Statistics projects the labor force participation rate for workers aged 75 and older will exceed 10% by 2026, while the number of workers aged 65 and older is expected to rise dramatically from 2016 to 2026. These are not small numbers. This is a structural shift in how America ages and works.
7. Age Discrimination Makes Re-Entry Painful for Many Returning Retirees
Here’s a frustrating irony. Many retirees want to go back to work, they’re motivated, experienced, and genuinely ready, yet the job market doesn’t always roll out the welcome mat. Age bias remains a persistent and well-documented obstacle.
Age discrimination against older workers is a persistent problem. Its negative impact on getting and keeping jobs is detrimental to a worker’s financial security, retirement security, and ability to access benefits like health insurance.
About two-thirds of workers age 50-plus have reported seeing or experiencing age discrimination in the workplace, a proportion that has not changed since 2024. In fact, roughly one in five workers 50-plus feel like they are being pushed out of their job because of their age.
Research shows that more than three-fifths of hiring managers are skeptical about hiring retirees, though they also acknowledge potential benefits. According to those hiring managers surveyed, the main reason for hiring a retiree is their many years of experience, and nearly the same number feel that retirees can make great mentors in the workplace. Yet the biggest reason cited for not hiring a retiree is cultural fit concerns. It’s a real tension, and honestly, it’s one that employers need to address head-on.
8. Remote Work Has Made Returning to the Workforce Far More Accessible
One of the quietly transformative forces behind the unretirement trend is flexible and remote work. Physical limitations, commuting distances, and mobility challenges used to make full reentry impractical for many older adults. That’s changing fast.
Of those seniors considering returning to work, the vast majority intend to work part-time. Additionally, more than half would be looking to switch industries entirely, while nearly a third of seniors considering a return to work say they would prefer to be fully remote.
For many retirees, returning to work does not always mean going back full-time. It often means part-time or flexible roles that help supplement income without fully reentering the workforce. Bureau of Labor Statistics data shows that about 38% of employed workers age 65 and older worked part-time in 2024, emphasizing how common that shift has become.
Think of remote work as the ramp that was missing from the entrance to the workforce for older adults. It didn’t just make work possible again. For some retirees, it made work genuinely appealing for the first time in years. The autonomy, the flexibility, and the lack of a grueling commute? That’s a very different proposition than punching a time card at 62.
9. Social Security Strategy Is Driving Some Retirees Back to Work Deliberately
Not every retiree returning to work is doing so out of desperation. Some are making a very calculated financial move, one that involves delaying Social Security benefits to maximize their long-term income. It’s a strategy more retirees are becoming aware of.
Some of the largest financial benefits of additional years of work are delaying retirement account withdrawals and delaying claiming Social Security benefits. Delaying retirement just for a few years increases the possibility of retirement success sustainability.
Having additional years of earned income can also give workers more time to contribute to their savings, especially since many workers are likely eligible to make catch-up contributions at this stage of life. In 2025, those age 50 or older can contribute an additional $7,500 to their 401(k) plan each year, as well as an extra $1,000 across Traditional and Roth IRAs combined.
It’s a numbers game, and a powerful one. Delaying Social Security from age 62 to 70 can increase monthly benefits significantly over a lifetime. For someone in good health, returning to part-time work for even a few years to delay claiming can be worth tens of thousands of dollars in total lifetime income. That’s not boredom. That’s smart financial planning.
10. The Very Definition of Retirement Is Being Radically Redefined
Perhaps the deepest truth in all of this data is that the old concept of retirement – a clean, permanent exit from working life at 65 – is being quietly retired itself. A new, more fluid model is emerging, and it actually looks healthier for many people.
Retirement, for many, isn’t the end of work, but rather an opportunity to redefine it on their own terms. This shift highlights a broader trend: today’s retirees are redefining what it means to age by staying engaged, active, and purpose-driven in their later years, whether through work, volunteering, or lifelong learning.
Many retirees see part-time work as a good transition strategy into retirement. Overall, more than half of retirees want to continue working in some form, while a significant minority would stop working all at once.
For households planning ahead, the takeaway is not that retirement is disappearing. It is that flexibility is becoming part of financial stability. Working longer, returning part-time, or consulting after retirement is increasingly a way to manage risk, not a sign that something failed. That reframing matters enormously. It removes the stigma and opens the door to a more honest conversation about what later life can and should look like.
The Real Picture Is More Complicated Than “They Were Just Bored”
The unretirement trend is one of the most significant shifts happening in the American workforce right now, and it deserves a far more nuanced conversation than it typically gets. Yes, boredom plays a role. But inflation, healthcare costs, identity, loneliness, Social Security strategy, and the quiet failure of defined-contribution retirement plans are doing far more of the heavy lifting.
A 2025 AARP survey found that roughly half of those who unretired cited financial necessity or a poor economic outlook as their primary reason for returning to work, which tells you something important: the dominant narrative about retirees returning for fun and stimulation is only a small slice of the real picture.
The honest takeaway is this: if you are planning for retirement, the smartest thing you can do right now is plan for more than one version of it. Plan for the version where you never work again. Plan also for the version where working a little, on your own terms, ends up being the most financially and emotionally fulfilling chapter of your life.
Retirement is no longer a destination. For a growing number of Americans, it’s become a starting point for something entirely new. What does that mean for how you’re thinking about your own future?
