Part-Time Work Share Reaches 42% in May Labor Market
ADP chief economist Nela Richardson flagged part-time employment at 42% in May as a concern, noting it is higher than five years ago.
Objective Facts
US private employers added 122,000 jobs in May 2026 according to ADP. ADP chief economist Nela Richardson flagged that the part-time share reached 42% in May, which represents a higher share than the firm was tracking five years ago. Pay for job stayers held steady at 4.4% year-over-year while job-switchers saw annual pay growth edge down to 6.5%. As of April, 4.9 million people were employed part-time for economic reasons, meaning they would have preferred full-time employment but faced reduced hours or inability to find full-time jobs. The broader labor market context shows both improvements in headline job growth and underlying concerns about the quality and composition of employment being created.
Left-Leaning Perspective
The National Women's Law Center reports that part-time workers earn 19.8% less per hour than full-time counterparts in the same industry and occupation, with specific examples including entry-level retail salespersons earning $3 less per hour and office support workers earning $5.40 less per hour than full-time equivalents. The Economic Policy Institute notes this part-time wage penalty reaches 29.5% for workers seeking but unable to secure full-time employment. The NWLC emphasizes that nearly six in ten part-time workers are women, with 28.9% of all working women in part-time roles versus 18.2% of men, and women constitute nearly two-thirds of part-time workers while bearing the brunt of the wage penalty despite smaller individual penalties than men. Part-time workers often lack employer-provided benefits eligibility, and research shows up to 40% of part-time workers would prefer more hours, with half of those in service occupations seeking additional hours that BLS counts as "noneconomic" reasons. Left-leaning coverage, citing Indeed Hiring Lab data, notes that posted wages for salaried roles grew 2.9% while hourly pay rose only 1.7%, and as consumer prices surged 3.8% in April while average hourly earnings rose 3.6%, the wage growth gap between hourly earners and salaried workers with benefits is critical context for assessing labor market quality.
Right-Leaning Perspective
The U.S. Treasury's May 2026 statement emphasized that employment growth in early 2026 underscores labor market resilience, with average monthly private payroll growth surging in Q1 2026 to over 2.5 times above the monthly average in 2025. The Treasury highlighted that worker wages continue to outpace inflation despite elevated price levels from the Iran conflict, with average hourly earnings up 3.5% over the year ending March 2026, and stressed that wages continue to outpace inflation. Fox Business reported Navy Federal Credit Union economist Heather Long stating the ADP jobs report showed healthcare made up nearly half of jobs but increases occurred in almost every industry, creating a better picture for job seekers than the previous year, with the most encouraging news being that over half of job gains were at smaller firms that were the first to cut back after tariffs but whose hiring now represents a vote of confidence in the economy. Treasury noted that other indicators point to stable labor markets, including the layoffs rate remaining stable and low, initial unemployment claims remaining exceptionally low by historical standards, and the hires rate remaining remarkably stable for over two years. RBC Economics noted a strong payroll gain and unemployment rate drop signal solid labor market footing, with the silver lining that the US needs to add fewer jobs for the unemployment rate to hold steady since breakeven employment is significantly lower than a year ago.
Deep Dive
ADP chief economist Nela Richardson's comment that the 42% part-time share is "a small fly in the very solid ointment of the labor market" captures the core tension: headline employment numbers beat expectations and hiring was broad-based, yet the composition of job creation appears tilted toward part-time roles. ADP's own pay trends research indicates that in 2025-2026, approximately 45% of workers were employed part-time—six percentage points higher than in 2019—reflecting a structural shift in work arrangements. BLS data shows 4.9 million people working part-time for economic reasons as of April, up 445,000 from prior months, with research indicating these workers would have preferred full-time employment but faced reduced hours or inability to find full-time jobs, while some sources note this measure may undercount those wanting more hours. The Economic Policy Institute documents that part-time wage penalties are most severe—29.5%—for workers who want full-time hours but cannot secure them, suggesting the quality-of-jobs concern is empirically grounded. Both left and right acknowledge demographic headwinds: a shrinking pool of workers from retirements, fewer births, and reduced immigration—which lowers the breakeven employment rate needed to maintain stable unemployment but also places strain on government finances through reduced tax revenues. The key unresolved question is whether current part-time employment shares reflect optimal labor market adjustment to demographic constraints or problematic employer cost-avoidance accelerated by healthcare costs and automation. Treasury and analyst projections note AI investment has gone toward equipment and software rather than job creation, with no large-scale displacement yet, though jobs with higher AI exposure show slower growth especially among younger workers. This suggests the May 2026 part-time employment level may reflect both genuine structural change in workforce preferences and labor supply constraints alongside possible employer strategies to manage costs and risks in an uncertain environment.
