Others offer a broader range of services. For example, a single agency may provide permanent employees, independent contractors and temporary workers. Administer job skills and knowledge tests. Verify credentials and check references. Either way, it's the employer that pays the agency's fee, not the employee.
Fees are either a flat rate or, more typically, a percentage of the job's salary.
Whatever services you decide to seek, it's important to deal with an agency known for quality service. Be sure to ask for references and also seek recommendations from other businesses in your industry and your community. The agency's thoroughness in exploring the needs of the business and the qualifications of candidates is a key factor. One-shot placement fees may be higher than rates for ongoing placement support. The clearer you can be about precisely the skills and experience needed for the job, the more likely it is you'll get someone who will work out.
