What are the two tracks women have to choose from when climbing the career ladder in most companies?

Women have to choose between the "fast track" and the "mommy track" when climbing the career ladder. In fast track, employees are expected to work extra hours, ask for extra work, and work nights and weekends. The fast track seems to ask women to forget that they have families, or place families second in importance after jobs, rather than helping families balance home and work responsibilities. Since women still shoulder most of the housework and child rearing in most homes, if they choose the fast track they will have to sacrifice at least some of these personal responsibilities. What happens in the mommy track is just the opposite. When women try to balance family responsibilities with work responsibilities, they receive fewer promotions or raises, and are often stuck in low-wage jobs.
