How to compare them

For coverage and turnaround time, ask each agency:

• How many branches do you have in my region?
• What roles can you fill fastest?
• What is your average time-to-submit and time-to-fill?
• Do you have a ready bench of pre-screened candidates?
• What industries do you specialize in locally?
• What is your fill rate for same-day or next-day requests?
• Do you offer 24/7 support for urgent orders?

Quick rule of thumb

• Best overall coverage: Randstad, Adecco, Manpower
• Best specialized office/professional staffing: Robert Half, Kelly Services
• Best industrial/warehouse staffing: Aerotek, Manpower, Adecco
• Best IT/professional contract staffing: Insight Global, Robert Half, Kelly Services

Practical advice

If turnaround time matters most, don’t rely on brand alone. The best local branch and recruiter often matters more than the national name. A smaller agency with a strong local candidate pool may outperform a big firm in your city.
