Marissa Mayer was pregnant when she took the helms of Yahoo! One of her changes was to revamp the company's maternal and paternal leave policies to make it more in line with her former employer. Under her mandate, new fathers at Yahoo! can now take eight weeks of paid paternal leave and new mothers can take an additional eight weeks. On top of that, the new parents get $500 to buy needed items like groceries and baby clothes.
