How to Get a Company's Attention on Women's Pay
In a recently released study of the 10 industries that employed the most
women from 1995 to 2000, the General Accounting Office found that the
gap between the salaries of men and women had widened for managers in
seven of those sectors. The largest widening was in entertainment and
recreational services, where female managers were earning just 62 cents
for every dollar made by a male manager in 2000, down from 83 cents in
1995. Only three industries showed improvement for women — albeit slight.
The biggest gain was in educational services, where the figure rose to 91
cents on the dollar, from 86 cents.

The G.A.O. report is supported by other studies, including one conducted
by the Women's Research and Education Institute in Washington showing
that overall managerial salaries for women slipped to 71.3 cents in 2000
from 73 cents in 1995.

An obvious question arises from these findings: Is it is ever ethically
justifiable for executives, men or women, who make compensation decisions
to pay women less than they pay men for doing the exact same job? There's
no gray area here. The answer is no.
