Because almost every industry—from manufacturing to health care—uses temporary workers or consultants, employment opportunities abound. According to the Occupational Outlook Handbook, this field is expected to grow about 19 percent, or faster than the average for all occupations, through 2018. This industry is expected to add about 600,000 new jobs through 2018. Most new jobs will occur in the largest occupational groups: office and administrative support, production, and transportation and material moving. There will also be many opportunities in specialized fields such as nursing, health care, accounting, and information technology.
