Philadelphia Could Become Third U.S. City To Require Paid Sick Days For Workers | Today, the Philadelphia City Council voted to require employers to provide workers with paid sick leave, which would make Philadelphia the third city with such a requirement, along with San Francisco and Washington D.C. The bill passed the city council by a 9-8 vote. Earlier this month, Connecticut became the first state to require paid sick leave for workers. The U.S. loses $180 billion in productivity annually due to sick employees attending work and infecting others. Mayor Michael Nutter may veto the bill.
