Checking the Marketplace's Daily Pulse, our offbeat take on the health of the U.S. economy.

There's word today that just over half of working mothers in the U.S. get paid maternity leave from their employers. This includes women who have to use their sick pay and vacation time in addition to any pay from the boss.
