In most of the developed world, when people get sick or have a sick child, they take a sick day and take care of themselves and their families, keeping their co-workers, customers and clients safe. And they rest comfortably, knowing that getting sick won’t mean they can’t pay the rent or provide their children with needed school supplies. That’s the way it should be. In most of the advanced world, paid sick days are a right that protects working families, while at the same time boosting businesses and the economy.

In just two weeks, the movement for paid sick days has seen three victories—in Portland, Ore., Philadelphia and, most recently, New York City. Local coalitions in each place encountered fierce opposition, and yet the wave of wins continues.

Why now?

Because people need it, demanded it and built the capacity to win.
