B. Wages and Benefits—In 2012, private-sector unionized workers received, on
average, wages that were 27% higher than nonunion counterparts.
1. The union-nonunion gap is most likely overestimated due in part to the
ease of organizing higher skilled (therefore more highly paid) workers.
The “union threat” more than likely causes an underestimation of the
differences. The net union advantage in wages are 10 to 15%.
2. Unions influence the way in which pay is given (across-the-board wages
on top of occupational wage rates). Promotions are in large part based on
seniority.
C. Productivity
1. Unions are believed to decrease productivity in three ways:
a. The union pay advantage motivates management to use more
capital per worker, which is inefficiency.
b. Union contracts may limit workload, and so on.
c. Strikes and other job actions result in some lost productivity.
2. Unions, alternatively, may increase productivity:
a. Unions provide more efficient communication with management,
which may reduce turnover.
b. The use of seniority decreases the competition between workers.
c. The presence of a union may encourage management to tighten up
in terms of consistency on work rules, and so on.
3. Overall, studies have concluded that union workers are more productive
than nonunion workers although the explanation is not clear.
D. Profits and Stock Performance—These may suffer under unionization if costs are
raised or decrease investment by a greater amount. Recent studies have shown
negative effects on profit and shareholder wealth. These research findings
describe the average effects of unions. The consequences of more innovative
union-management relationships for profits and stock performance are less clear.
X. The International Context—The United States has both the largest number of union
members and the lowest unionization rate of any Western European country or Japan,
aside from France and Korea (Text Table 14.15). A number of potential explanations
exist.
