Because Mommy Works is a 1994 television film directed by Robert Markowitz.
The film confronts the issue of women being denied custody rights during divorce partly or solely because they work at jobs outside the home, allegedly making them less available as maternal caregivers.
It focuses in particular on the added custodial challenge that working women face if their former husband has remarried a woman who does not have a job.
[1] The film was inspired by a true story that appeared in McCall's Magazine in 1992, "Why a Good Mother Lost Custody of her Child" by author Cameron Stauth.
The article was about a custody case in Eugene, Oregon, that involved a female teacher who lost custody of her young son, primarily because her husband had remarried a woman who did not work outside the home.
