In two white-collar major occupational groups, average hourly earnings were higher for nonunion than for union workers.

The second was sales workers, among whom nonunion workers had average hourly earnings of $14.58, compared with $12.78 for their union counterparts.
Union workers are considered those whose wages are determined through a collective bargaining process.
BLS Defines collective bargaining as a method whereby representatives of employees (unions) and employers determine the conditions of employment through direct negotiation, normally resulting in a written contract setting forth the wages, hours, and other conditions to be observed for a stipulated period (e.g., 3 years).
In 2002, 13.2 percent of wage and salary workers were union members, down from 13.4 percent (as revised) in 2001.
The number of persons belonging to a union fell by 280,000 over the year to 16.1 million in 2002. The union membership rate has steadily declined from a high of 20.1 percent in 1983, the first year for which comparable union data are available.
