• Employment services ranks among the industries projected to grow the fastest and to provide the most new jobs.
• Most temporary jobs in this industry require only graduation from high school, while some permanent jobs may require a bachelor's or higher degree.
• Temporary jobs provide an entry into the workforce, supplemental income, and a bridge to full-time employment for many workers.

The employment services industry has three distinct segments. Employment placement agencies list employment vacancies and place permanent employees. Temporary help services, also referred to as temporary staffing agencies, provide employees to other organizations, on a contract basis and for a limited period, to supplement the workforce of the client. Professional employer organizations are engaged in providing human resources and human resources management services to staff client businesses. They also assign workers to client locations, thereby assuming responsibility as an employer while providing a cost-effective approach to the management and administration of the human resources functions of its clients on a contract basis.

The typical employment placement agency has a relatively small permanent staff, usually fewer than 10 workers, who interview jobseekers and try to match their qualifications and skills to those being sought by employers for specific job openings.

In contrast to the smaller employment agencies, temporary help agencies typically employ many more workers. Temporary help services firms provide temporary employees to other businesses to support or supplement their workforce in special situations, such as employee absences, temporary skill shortages, and varying seasonal workloads. Temporary workers are employed and paid by the temporary help services firm but are contracted out to a client for either a prearranged fee or an agreed hourly wage. Some companies choose to use temporary workers full time on an ongoing basis, rather than employ permanent staff, who typically would receive greater salaries and benefits. As a result, the overwhelming majority of workers in the temporary help services segment of the employment services industry are temporaries; relatively few are permanent staff.

Professional employer organizations specialize in performing a wide range of human resource and personnel management duties for their client businesses, including payroll processing, accounting, benefits administration, recruiting, and handling labor relations. Employee leasing establishments, which are a type of professional employer organization, typically acquire and lease back some or all of the employees of their clients and serve as the employer of the leased employees for payroll, benefits, and related purposes.

Traditionally, firms that placed permanent employees usually dealt with highly skilled applicants, such as lawyers or accountants, and those placing temporary employees dealt with less skilled workers, such as administrative support occupations. However, temporary help services firms increasingly place workers who have a range of educational backgrounds and work experience because businesses now are turning to temporary employees to fill all types of positions—from administrative to managerial, financial, professional, and production.
