In December 2011, private industry union workers earned more per hour than their nonunion counterparts in all major occupational groups except management, professional, and related occupations.
Management, professional, and related
Natural resources, construction, and maintenance
Production, transportation, and material moving
Sales and office
Union workers in natural resources, construction, and maintenance occupations earned $29.69 per hour, while nonunion workers in that occupational group earned $18.71 per hour. Unionized workers in production, transportation, and material moving occupations earned $21.78 per hour, compared with $14.40 per hour for nonunion workers. Unionized sales and office workers earned $16.60 per hour, compared with $15.98 for nonunionized sales and office workers. In service occupations, union workers earned $16.17 per hour compared with $10.16 for nonunion workers.
In management, professional, and related occupations, union workers earned less per hour ($32.95) than nonunion workers in these occupations ($35.70). The wage advantage for nonunion workers in this group reflects the concentration of union workers in certain relatively low-paying occupations in business and financial operations, such as claims adjusters, accountants, and training specialists
