TrueBlue / PeopleReady

There’s no single “best” staffing agency in the U.S. — the right one depends on your industry, role level, and whether you’re looking for temp, contract-to-hire, or direct placement. But these are the most widely used, reputable staffing brands by category:

🏭 General & Light Industrial

Best for warehouse, manufacturing, logistics, and entry-level labor.

• Manpower
• Adecco
• Kelly Services
• Randstad
• TrueBlue / PeopleReady

These are the big national players that fill high-volume temp shifts quickly.

💼 Office, Admin & Finance

Best for administrative assistants, accounting clerks, office managers, and junior finance.

• Robert Half (and its finance arm Accountemps)
• Aston Carter
• Beacon Hill Staffing Group
• Randstad USA
• LaSalle Network (strong in Chicago, but places nationally)

Robert Half is probably the most recognized name in finance/accounting temp and permanent placement.

💻 Technology & IT

Best for software engineers, IT support, DevOps, cybersecurity, and cloud roles.

• TEKsystems
• Insight Global
• Robert Half Technology
• Kforce
• Motion Recruitment (great for startup/contract work)

If you’re a developer or IT pro, TEKsystems and Insight Global place a massive number of contract workers every year.

🏥 Healthcare & Nursing

Best for RNs, LPNs, allied health, and travel contracts.

• AMN Healthcare
• Aya Healthcare
• Cross Country Healthcare
• Maxim Healthcare Services

Aya is one of the most popular for travel nurses because of its mobile app and transparent pay packages.

⚙️ Engineering & Technical

Best for mechanical, electrical, civil, and design engineering roles.

• Actalent (Aerotek’s engineering-focused spinoff)
• Aerotek
• Belcan
• Kelly Engineering
• Insight Global

🎨 Creative, Marketing & Digital

Best for designers, copywriters, marketers, and brand/creative talent.

• Creative Circle
• Aquent
• 24 Seven
• The Mom Project (also great for flexible/remote roles)
• Mediabistro (for media and marketing)

🧑‍💼 Executive Search (Senior Leadership)

For VP/C-suite direct placement, these are the top retained search firms:

• Korn Ferry
• Spencer Stuart
• Heidrick & Struggles
• Russell Reynolds Associates

These aren’t for temp jobs — they’re used by companies hiring executives.

Quick tip

If you are a job seeker:

• Use LinkedIn, Indeed, and ZipRecruiter to see which agencies are hiring in your field.
• Contact 2–3 niche agencies rather than all of them — staffing recruiters respond better when you fit their specialty.
• Many agencies also have “direct hire” divisions, so even if you don’t want temp work, they can place you permanently.

If you are a company hiring, the “best” agency usually comes down to:

• Speed → Manpower or TrueBlue
• IT contract staffing → TEKsystems or Insight Global
• Finance/accounting → Robert Half
• Travel nurses → Aya
• Engineering → Actalent

Bottom line: Robert Half, Manpower, Randstad, Aerotek, and TEKsystems are probably the five staffing brands people in the U.S. use most overall, but niche matters more than brand.
