Is there a wage penalty for motherhood? Research suggests so, showing that having a child has a negative impact on women's earnings, while fatherhood offers a wage bonus for men. For each child a woman has, her wages decrease by about 4 percent, whereas a man's wages rise by about 6 percent when he becomes a dad, perhaps because employers start to see these earners differently once they've become fathers.
Mothers get the short end of the stick when it comes to equal pay in the working world. But, contrary to popular belief, working mothers might actually make the best employees.
