We're not saying that employers discriminate against mothers because they don't like them.

Not mentioning that you have children, or trying to hide the fact, is obviously a limited strategy. We're doing another study now to try and determine whether companies with 'family-friendly' and 'work-life balance' policies are less likely to discriminate against mothers than employers that don't have such policies. But in the meantime, what I hear is the advice that mothers give each other.
