> In private industry, there is a different pattern among workers in this occupational group: those represented by unions earned an average of $32.95 per hour, while those not represented by unions earned $35.70 per hour. The wage advantage for nonunion workers in this occupational 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.
