Also, many firms have automated their inspection systems, using machinery installed at one or several points in the production process. The inspectors in these firms have generally been trained to operate this equipment. Working conditions vary from industry to industry. Most remain at one work station, but some travel from place to place to do inspections. Some may have to lift heavy objects.
Some inspectors work evenings, nights, or weekends.
In these cases, shift assignments generally are made on the basis of seniority. Overtime may be required to meet production goals. Employment Inspectors, testers, and graders held about 625,000 jobs in 1992. Almost 8 of every 10 worked in manufacturing industries, including industrial machinery and equipment, motor vehicles and equipment, primary and fabricated metals industries, electronic components and accessories, textiles, apparel, and aircraft and parts. Some worked in communications and utilities, wholesale trade, engineering and management services, and government agencies.
