CHG Healthcare

Assuming you’re in the U.S., the “best” staffing agency depends heavily on the job type. If you want brands people actually use—not obscure listicles—start with firms that show up consistently in SIA size rankings, Forbes/Statista reputation rankings, and ClearlyRated client/talent satisfaction awards. SIA’s 2025 U.S. largest-staffing-firm update lists Allegis Group, Aya Healthcare, Randstad, Insight Global, Kelly, Express, ManpowerGroup, Robert Half, Adecco, and CHG Healthcare among the top 10 by 2024 U.S. staffing revenue.

Best staffing agencies by use case

My short “start here” list

If you don’t know where to begin, I’d use this shortlist:

1. Robert Half — best first stop for accounting, finance, admin, legal, marketing/creative, and many professional temp-to-hire roles.
2. Randstad — strong broad-market generalist for office, industrial, finance, tech, and enterprise staffing.
3. Kelly — especially good for education, science, engineering, technology, and professional/industrial roles.
4. Manpower — very good for temp, office, light industrial, and broad workforce needs.
5. Adecco — good for high-volume temp, logistics, customer service, industrial, and some professional roles.
6. Insight Global — strong for IT, business operations, finance/accounting, and contract professional roles.
7. TEKsystems — one of the best-known tech staffing brands, especially for IT infrastructure, support, software, and enterprise projects.
8. Aerotek — strong for manufacturing, logistics, construction, aviation, facilities, and skilled trades.
9. Express Employment Professionals — good local-market option for office, industrial, and skilled trades, especially outside major coastal metros.
10. Aya Healthcare / AMN / CHG / Jackson Healthcare — use these if you’re in healthcare, travel nursing, allied health, or locum tenens.

Practical advice

Sign up with 2–4 agencies in your niche, not just one. For example: if you’re in accounting, try Robert Half + Randstad + Insight Global; if you’re in tech, try TEKsystems + Insight Global + Kforce; if you want warehouse/logistics, try Aerotek + Adecco + Express.

Also: as a job seeker, be careful with any “agency” asking you to pay upfront. The FTC warns job seekers not to pay a fee to get a job and flags unsolicited texts, requests for bank/SSN details too early, and “pay to get paid” schemes as scam indicators. (consumer.ftc.gov)

Best Staffing Agencies (2026)

The "best" agency really depends on what you need — general/temp staffing, IT, healthcare, finance, executive search, or creative roles. Here's a breakdown of the brands people actually use most, based on current market data and specialty:

🏆 Largest & Most Widely Used (General/Global)

Adecco Group is the largest staffing firm globally by revenue, followed closely by Randstad and ManpowerGroup, with these industry leaders generating billions of dollars annually across multiple continents. Other major names people commonly turn to include Adecco USA, Randstad USA, Aerotek, Robert Half, Kelly Services, ManpowerGroup, and Spherion.

💻 IT / Tech Staffing

TEKsystems and Insight Global lead IT staffing. For reference, Insight Global places over 25,000 IT professionals annually across various industries, making them a leading staffing agency for IT recruitment. If you want data-backed rankings, one industry scorecard found KORE1 scoring 8.22/10 on a Placement Authority Score — the highest of ten IT-specialist firms scored, with Kforce ranking second (7.81) for tech + finance hiring, and TEKsystems ranking third (7.30) for enterprise volume. That methodology was based on a 7-factor methodology using independently verified public data across Clutch, Glassdoor, ClearlyRated, and third-party awards — so it's a reasonably credible benchmark, though note it's from a firm evaluating its own competitors.

🏥 Healthcare Staffing

Aya and CHG own healthcare staffing, making them the go-to names for travel nursing and clinical placements.

💰 Finance & Accounting

Robert Half dominates finance staffing — it's one of the most recognized names for accounting, finance, and admin roles.

🏗️ Industrial / Light Industrial

Express Employment and Aerotek run industrial staffing, both known for high-volume warehouse, manufacturing, and logistics placements.

🎨 Creative & Marketing

Aquent handles creative staffing, and boutique firms like 80Twenty are also popular for design/marketing talent.

👔 Executive Search

Korn Ferry tops executive search — the standard choice for C-suite and senior leadership recruiting.

Some market context

The staffing industry is huge and growing: the US staffing market hits $183.3B in 2026, with 224 firms each generating $100M+ in staffing revenue, and healthcare ($47.3B) and IT ($37.9B) as the two largest segments. On pricing, expect fees to be material — direct hire placements typically run 15-30% of first-year salary, while temp markups run 25-70%.

Bottom line recommendation

• General/enterprise hiring: Adecco, Randstad, ManpowerGroup, Kelly Services
• IT/tech: TEKsystems, Insight Global, Kforce, KORE1
• Healthcare: Aya, CHG
• Finance/accounting: Robert Half
• Industrial/warehouse: Express Employment, Aerotek
• Executive search: Korn Ferry
• Creative: Aquent, 80Twenty

If you tell me your industry, location, and whether you're hiring temp/contract vs. permanent, I can narrow this down further.

If you want the most widely used staffing brands, the strongest names in the results are Randstad, Allegis Group, Robert Half, Kelly Services, and Insight Global.

Here’s a practical shortlist by what people actually use them for:

For a more “real-world used” signal, review and award sites also point to firms like ClearlyRated-recognized agencies, Clutch-ranked firms, and Forbes temp staffing firms lists, which are useful for checking reputation and client satisfaction before choosing.

If you want the best overall picks, I’d narrow it to:

• Randstad for large-scale, general staffing.
• Robert Half for office, finance, and accounting roles.
• Allegis Group / TEKsystems for IT and technical hiring.
• Kelly Services for broad professional staffing.
• Aya Healthcare for healthcare staffing.

If you want, I can also rank the best staffing agencies by category: IT, healthcare, finance, warehouse/light industrial, or executive search.
