The "What Works for Women at Work" video series by University of California professor Joan C. Williams helps you spot the four patterns of gender bias that shape today's workplaces. The videos describe proven strategies successful women use to navigate subtle bias. Part 3 explores the biases that working moms often face – "the maternal wall." You may hear from coworkers that you're no longer committed or competent after having children. The video explains how you can fight those assumptions and be taken seriously as a professional.
