For decades, parents and educators have debated whether high school students should hold part-time jobs. Some argue that working builds responsibility and soft skills, while others worry it distracts from academics and extracurricular activities.
A recent study published in Research in Social Stratification and Mobility investigates this issue by tracking a single group of students from age 14 to 46. The research reveals that holding a job consistently throughout high school is linked to better career stability and higher wages in mid-life.
Working long hours as a teen, on the other hand, offers a different trajectory. The study indicates that heavy adolescent work schedules provide a temporary wage boost right out of high school but lower the chances of eventually earning a college degree.
Tracking Decades of Career Data
Much of the existing research on adolescent employment focuses on the short term. Prior studies have largely scrutinized how teen jobs affect high school grades, standardized test scores, or wages immediately after graduation.
Jeremy Staff of Pennsylvania State University and Jeylan T. Mortimer of the University of Minnesota wanted to look further down the road. They sought to understand if the habits and experiences formed in high school jobs translated to economic advantages decades later.
To measure employment, the researchers looked at two specific factors. The first was intensity, which tracked how many hours a student worked per week. The second was duration, which measured how many months a student remained consistently employed across the school years.
The researchers analyzed data from the Youth Development Study. This project followed an initial group of 1,010 ninth graders in St. Paul, Minnesota, starting in 1988. Participants completed surveys annually through high school and periodically until 2019.
Isolating the Impact of the Job
Teenagers who work long hours often come from different socioeconomic backgrounds than those who do not. To account for this, the researchers used a statistical matching method to pair students who shared similar starting points.
They matched students based on family income, parental expectations, early substance use, and ninth-grade academic records. This allowed the researchers to compare individuals with similar early life profiles to see how their different high school work schedules influenced their adult lives.
The Short-Term Gains of Intensive Work
The analysis showed that working at high intensity, defined as more than 20 hours per week, came with a mix of early gains and long-term costs. In the years immediately following high school, these intensive workers earned higher hourly wages than their peers who worked fewer hours.
This wage advantage faded as the workers reached their late twenties and thirties. The researchers also found that high-intensity workers were 41 percent less likely to eventually earn a bachelor’s degree compared to their matched peers.
Staff and Mortimer suggest that while heavy work hours integrate teenagers into the labor force quickly, they do not help them access the initial rungs of higher-paying, long-term career ladders. The early entry into full-time work often comes at the expense of higher education.
The Long-Term Benefits of Steady Work
Employment duration painted a different picture. Students who worked for a high number of months throughout high school saw sustained economic benefits into adulthood.
These high-duration workers reported higher wages across all adult age brackets measured in the study. By their mid-twenties, 62 percent of high-duration workers had landed a job they viewed as a career track, compared to 47 percent of those who worked less consistently.
Importantly, working for many months during high school did not reduce a student’s likelihood of earning a college degree. The researchers interpret this to mean that students who work consistently learn how to balance their employment with their academic responsibilities.
Finding the Right Balance
The researchers combined these two metrics to see which overall work pattern yielded the best results. They found that “steady” workers, those who worked nearly continuously but kept their hours under 20 per week, experienced the most favorable outcomes.
These steady workers had the highest odds of receiving a bachelor’s degree among all employment categories. By the time they reached ages 29 to 46, they also had the highest likelihood of holding a career-track job and earning higher wages.
The authors propose that steady, moderate work allows students to develop time management and reliability. A history of stable employment might also signal to future employers that a young person is a trustworthy and productive worker.
Parallels to Vocational Training
The authors note that these findings mirror trends seen in European vocational education systems. In countries with heavy vocational tracking, students who focus early on specific occupational skills often see initial employment advantages.
These early gains tend to flatten out over time compared to students who pursue general education and higher university degrees. Because the United States lacks a unified vocational system, intensive part-time work often serves as an alternative route into the labor force for students not planning to attend college.
The researchers argue that while this heavy work investment prevents early unemployment, it limits a worker’s ability to adapt to new technologies and higher-level roles later in life.
Changing Times for Teen Workers
For families navigating high school schedules, the findings point toward a balanced approach to adolescent employment. A job that offers steady, year-round work at moderate hours is associated with long-term economic stability.
Taking on too many shifts, however, appears to prioritize short-term cash over long-term educational attainment. The researchers note a few specific limitations to the data, as the study followed a single group of predominantly white students in one Midwestern city who entered the workforce during the strong economic climate of the 1990s.
The economic and social environment for teenagers has shifted considerably since this cohort was in high school. Today, college admissions pressures push many students toward unpaid extracurricular activities rather than paid employment.
The types of entry-level jobs available to teenagers have also changed. It remains an open question whether today’s high school workers will experience the exact same mid-life career trajectories as those observed in this three-decade study.
