Question: According to Dr. Sarah Beth Estes, sociology professor at the University of Cincinnati, and Dr. Jennifer Glass, sociology professor at the University of Iowa, working women who take advantage of family-friendly schedules can fall behind in wages. More specifically, the sociologists report that in a study of 300 working women who had children and returned to work and opted for flextime, telecommuting, and so on, these women had pay raises that averaged between 16% and 26% less than other workers ( Study: Face Time Can Affect Moms Raises, The Cincinnati Enquirer, August 28, 2001, p. A1).
