4. "You're Like a Superhero!"
Sure, this might seem like a compliment. But when you say it to a working mother who is expected to be like a superhero to make ends meet, it's short-sighted. Working women are often forced to bear the brunt of childcare, elderly care and even irrelevant help around the office, all while working full-time jobs. They wouldn't have to be like superheroes if society started accepting an equal division of household labor and paid women fairly for equal work.
What to Say Instead: Just don't say anything. Lend a helping hand and, if you're in a position to do so, give the woman equal pay.
