What Is a Temp Agency?
A temp agency (also called a temporary staffing agency or employment agency) is a company that connects workers with businesses that need short-term or contract employees. The agency handles recruiting, screening, and payroll, while the worker is assigned to the client company for a specific duration — from a single day to several months or even years.
Temp agencies serve as intermediaries in the labor market, solving a fundamental problem: businesses need flexible workforce capacity, and workers need job opportunities. The staffing industry generated over $200 billion in revenue in the US alone in 2024, employing approximately 12 million temporary workers.
How Do Temp Agencies Work?
The temp agency model involves three parties: the agency, the worker, and the client company.
Step 1 — Registration: Workers register with the agency, submit their resume, and complete skills assessments. The agency interviews candidates and verifies their qualifications, work history, and references.
Step 2 — Matching: When a client company requests temporary workers, the agency matches qualified candidates from their pool. The agency considers skills, experience, availability, location, and hourly rate requirements.
Step 3 — Assignment: The selected worker is assigned to the client company. They report to the client's workplace and follow the client's instructions, but they remain employed by the temp agency.
Step 4 — Payroll and administration: The temp agency handles all employment-related responsibilities — payroll, tax withholdings, workers' compensation insurance, and benefits (if applicable). The client pays the agency, and the agency pays the worker.
Step 5 — Completion: When the assignment ends, the worker returns to the agency's available pool for future assignments. Some temporary positions lead to permanent offers (temp-to-perm).
Types of Temp Agency Arrangements
Short-term temp: Assignments lasting days to a few weeks. Common for event staffing, seasonal work, or covering employee absences.
Long-term temp: Assignments lasting several months to a year or more. Common for project-based work or ongoing operational support.
Temp-to-perm (temp-to-hire): The worker starts as a temporary employee with the understanding that the position may become permanent after an evaluation period (typically 3-6 months). This is essentially a paid trial period for both parties.
Contract work: Higher-skilled positions with defined project scope and timeline. Common in IT, engineering, healthcare, and consulting.
Payrolling: The client identifies the worker, but the agency handles employment paperwork, payroll, and compliance. This is popular for companies that want to hire freelancers without the administrative burden.
How Much Do Temp Agencies Charge?
Temp agencies charge the client company a markup on top of the worker's pay rate. This markup covers the agency's costs and profit margin.
Typical markup: 25-100% of the worker's hourly rate, depending on the industry, skill level, and arrangement type.
| Role Type | Worker Pay | Client Pays | Markup |
|---|---|---|---|
| General labor | $15/hr | $22-25/hr | 47-67% |
| Administrative | $18/hr | $27-32/hr | 50-78% |
| Skilled trades | $25/hr | $38-45/hr | 52-80% |
| IT/Technical | $45/hr | $65-85/hr | 44-89% |
| Healthcare | $35/hr | $55-70/hr | 57-100% |
The markup covers: employer payroll taxes (7.65% FICA), workers' compensation insurance (1-10% depending on industry risk), unemployment insurance, agency overhead, recruiter salaries, and profit margin.
Workers are NOT charged by reputable temp agencies. If an agency asks you to pay a fee to register or be placed, it's a red flag — legitimate agencies make their money from client markups.
