Disposable Workers: How a Growing Segment of U.S. Employees Lacks Career Prospects

Scope of the Disposable Workforce
MIT Professor Emeritus Paul Osterman defines “marginal workers” as employees with no career prospects at their organizations. His research shows marginal workers comprise about 17 % of U.S. employees; 12 % are contract workers, 5 % are organizational freelancers, and just over 1 % are gig workers. Together they represent more than 35 % of the labor force—roughly 55 million of 162 million workers. The term “disposable workers” covers all three categories because firms treat them as interchangeable tools for cost control.
Background & Context
The rise of disposable workers follows a decades-long shift toward variable labor costs. Employers rely on contingent arrangements to gain flexibility, reduce benefits obligations, and avoid the fixed expenses of permanent staff. The Affordable Care Act’s 2014 employer-shared responsibility provision, which requires health insurance for workers clocking 30 hours or more per week, coincided with an increase of about 500,000 part-time positions in low-wage sectors such as retail, hotels, and restaurants.
Data & Statistics
| Category | Share of Workforce | Key Characteristics |
|---|---|---|
| Marginal workers | 17 % | No promotion ladder, high turnover |
| Contract workers | 12 % | Employed by staffing firms, assigned to client sites |
| Organizational freelancers | 5 % | Work for firms without being on payroll |
| Gig workers (platform-based) | >1 % | Algorithm-managed assignments |
| Total “disposable” labor | >35 % | ? 55 million workers |
| Union membership | ? 6 % | Limited collective bargaining reach |
| ACA penalty (2026) | US$3,340 per uninsured employee | Incentivizes part-time hiring |
Surveys of over 6,000 workers and interviews with nearly 100 employees, employers, and policymakers underpin these figures. Contractors and marginal workers earn less and report lower job satisfaction than regular employees, while freelancers are more satisfied because of greater schedule control.
Official Statements & Responses
Osterman says firms maintain a sizable disposable workforce because the financial benefits outweigh the perceived value of employee commitment. He notes that artificial intelligence may intensify the trend by increasing uncertainty about staffing needs. He proposes remedies such as stronger union representation, advocacy campaigns that have raised minimum wages, consumer pressure on large corporations, and policies that clarify worker classification and expand portable benefits.
Why It Matters
The expansion of disposable labor has measurable consequences. Workers in marginal and contract roles receive lower wages—part-time earnings are about 20 % below comparable full-time wages, with an additional 5 % gap when benefits are considered. Higher turnover reduces firms’ incentives to invest in training and erodes institutional knowledge. Studies link the use of contract cleaners to higher hospital infection rates and associate contractor reliance with increased industrial accidents. At the macro level, a large share of the workforce lacking clear career ladders can decouple wage growth from experience and skill acquisition.
What’s Next
Osterman suggests a multi-pronged approach: expanding union membership, enacting clearer legal definitions of employee status, and promoting portable benefit schemes. Consumer-driven campaigns that have pushed higher minimum wages may also be leveraged to improve conditions for marginal and contract workers. Sustained public attention, he argues, is essential to prevent further entrenchment of a labor market where a substantial portion of employees remain “disposable.”
