NYC: Paid sick leave is now the law.

The Washington Post reports:

It will now be much easier for many New Yorkers to take a sick day from work. Early Thursday, lawmakers overrode a veto by Mayor Michael Bloomberg to pass a law that would require businesses to offer paid sick leave for their workers. The benefit will go into effect in 2014 for employees of businesses with 20 or more workers and at a later date for smaller employers; it could be postponed if the city’s economy takes a big turn for the worst. Some businesses, such as struggling manufacturing firms, are exempt.

Why are some businesses exempt??? Who was paid off? Whatever happening to equal protection under the law.
