Underemployment
What Is Underemployment?
Underemployment is a measure of labor utilization that includes workers who are highly skilled but working in low-paying or low-skill jobs, and part-time workers who would prefer to work full-time.
The headline unemployment rate (U-3) answers a simple binary question: Do you have a job? If the answer is "yes"—even if that job is one hour a week walking dogs—you are considered employed. However, this binary distinction fails to capture the nuance of the modern labor market. Underemployment is the gray area between full employment and unemployment. It measures the extent to which the labor force is being utilized effectively. Underemployment manifests in two primary forms: 1. **Visible Underemployment (Hours-Based):** This occurs when a worker wants a full-time job (typically 35+ hours/week) but can only find part-time work. They are "involuntary part-time workers." During recessions, companies often cut hours instead of firing staff to save costs, causing this metric to spike. These workers are technically employed, but they are earning significantly less than their potential and are likely struggling to make ends meet. 2. **Invisible Underemployment (Skills-Based):** This is more insidious and harder to measure. It occurs when a worker is employed in a job that does not require their level of education or experience. A classic example is a college graduate with a degree in engineering working as a bartender. They are working full-time, so they don't show up in hours-based statistics, but their human capital is being wasted. This "malemployment" leads to lower lifetime earnings, skill atrophy, and lower overall economic productivity. Economists care deeply about underemployment because it reveals "slack" in the labor market. If the unemployment rate is low (e.g., 3.5%) but underemployment is high, it means there is still a massive pool of available labor. Employers don't need to raise wages to attract workers; they can just offer full-time hours to the part-timers or hire the overqualified barista. This explains why wage growth can remain stagnant even when the economy appears to be at "full employment."
Key Takeaways
- It captures the "quality" of employment, not just the quantity, revealing hidden slack in the labor market.
- Visible underemployment includes employees working fewer hours than they want (involuntary part-time).
- Invisible underemployment involves a mismatch between a worker's skills/education and their job requirements (e.g., a PhD driving for Uber).
- The U-6 unemployment rate is the broadest measure used by the Bureau of Labor Statistics (BLS) to track this phenomenon.
- High underemployment suppresses wage growth and can lead to long-term "scarring" of workers' earnings potential.
Measuring Underemployment: U-3 vs. U-6
In the United States, the Bureau of Labor Statistics (BLS) publishes six measures of labor underutilization, ranging from U-1 to U-6. The official unemployment rate is U-3. The measure that captures underemployment is U-6, often called the "real" unemployment rate. * **U-3 (Official Rate):** Total unemployed (actively looking for work) as a percentage of the civilian labor force. * **U-6 (Broadest Measure):** Includes: 1. **The Unemployed (U-3):** People without jobs who are actively looking. 2. **Marginally Attached Workers:** People who are not in the labor force, want and are available for work, and have looked for a job sometime in the prior 12 months. They are not counted as unemployed because they haven't looked in the last 4 weeks. 3. **Discouraged Workers:** A subset of the marginally attached who have given up looking specifically because they believe no jobs are available for them. 4. **Part-Time for Economic Reasons:** People employed part-time because their hours were cut or they were unable to find a full-time job. The gap between U-3 and U-6 is a critical indicator. In a healthy economy, the gap is small. In a recovering economy, U-3 might fall quickly (people get *any* job), but U-6 stays high (those jobs are bad). For example, after the 2008 financial crisis, the U-6 rate remained elevated for years, signaling deep structural weakness despite the headline recovery.
Causes and Long-Term Consequences
Underemployment is driven by both cyclical and structural factors:
- Recessions and "Labor Hoarding": Companies cut hours to survive downturns, creating a backlog of underemployed workers that takes years to clear.
- Technological Displacement: Automation and AI replace routine cognitive tasks, forcing mid-skill workers into lower-skill service jobs.
- Credential Inflation: Employers demand degrees for jobs that previously didn't require them, creating an artificial mismatch.
- Scarring Effects (Hysteresis): Workers who graduate into a recession and start essentially "underemployed" often never catch up. They lose out on critical early-career skill development and wage progression, suffering a permanent earnings penalty known as "scarring".
- Brain Drain: High invisible underemployment drives talented workers to move to other regions or countries where their skills are valued, hollowing out local economies.
Real-World Example: The "Lost Generation" of 2008
The aftermath of the 2008 Financial Crisis provides a stark example of underemployment's long tail.
Important Considerations for Policy
Policymakers (like the Federal Reserve) must look beyond U-3. If they raise interest rates to fight inflation while U-6 is still high, they risk choking off the recovery for the most vulnerable workers. The "Phillips Curve" (the trade-off between unemployment and inflation) may be broken or flattened by underemployment. It suggests the economy can sustain lower headline unemployment than previously thought without triggering inflation, simply because there is so much hidden slack (underemployed workers ready to step up).
FAQs
No. Many people (students, parents, retirees) specifically choose part-time work for work-life balance. This is "voluntary part-time" and is not considered underemployment. The BLS specifically tracks "Part-Time for Economic Reasons" to distinguish the two.
Yes, significantly. Studies show that underemployed workers suffer from depression, anxiety, and low self-esteem at rates similar to the unemployed. The psychological toll of feeling "stuck" or believing your potential is wasted is profound.
Severely. Underemployed workers often cannot qualify for mortgages or afford rising rents. This delays household formation (millennials living with parents) and suppresses demand for starter homes.
Sometimes. If your hours were cut significantly by your employer (partial unemployment), you may be eligible for partial benefits in some states. However, if you are "invisibly underemployed" (working full-time but in a low-paying job), you generally do not qualify for unemployment insurance.
The Bottom Line
Underemployment is the "dark matter" of the labor market—a massive, invisible force that explains why many people feel the economy is bad even when the headline numbers say it's good. For economists, it solves the puzzle of missing wage inflation. For workers, it represents a loss of potential and a source of deep frustration. Understanding the difference between U-3 and U-6 is essential for anyone trying to grasp the true health of the economy. It reminds us that a job is not just a binary status; it is a spectrum of utilization, and for millions, that utilization is far too low.
