Not just a glass ceiling, but a mommy wall

It's almost Mother's Day and Ellen Goodman discusses the bias against "moms" in the office.

Here's a Mother's Day card from a study just published by Shelley Correll in the American Journal of Sociology. Correll performed an experiment to see if there was a motherhood penalty in the job market. She and her colleagues at Cornell University created an ideal job applicant with a successful track record, an uninterrupted work history, a boffo resume, the whole deal.

Then they tucked a little telltale factoid into some of the resumes with a tip-off about mom-ness. It described her as an officer in a parent-teacher association. And -- zap -- she was mommified.

Moms were seen as less competent and committed. Moms were half as likely to be hired as childless women or men with or without kids. Moms were offered $11,000 less in starting pay than non-moms. And, just for good measure, they were also judged more harshly for tardiness.
