My 90 year-old mother used to tell me that moms are only allowed to be sick for one day – after that they have to get back to taking care of everyone else. Too bad that the nasty germs don’t always pay attention to the one-day rule. And to make matters tougher, nowadays, taking care of everyone else doesn’t just include the kids, it more often than not includes taking care of business at work. That’s why working moms in New York City are uniting on the front lines of the legislative battle to win the right to earn paid sick time on their jobs. Huh? Doesn’t everyone already get paid sick leave...
