At my company, female employees with young children never get promoted. Although the company doesn't seem to treat men better than women generally, mothers really get left behind. When I applied for a management position, my supervisor asked me whether I was willing to put in the longer hours the position requires, given that I have kids at home. He also questioned whether I'd "really" be willing to travel when the time came to attend company meetings in other cities, and talked about how difficult his wife found it to leave their kids overnight. I've never given my employer any reason to think I wouldn't do my job. All of my performance evaluations are stellar, and I'm ready for more responsiblity. Not that it's any business of my company's, but my husband handles most of the child care in our family. Isn't this sex discrimination?
