WILLIAMSBURG - Mayor Bill de Blasio signed legislation Thursday to expand paid sick leave to companies with at least five employees.

The mayor opted to sign his first bill into law at Steve's Craft Ice Cream in Williamsburg rather than at City Hall. He wanted to use the business as an example of a booming business that already offers their workers paid sick days.

The new law requires businesses with five or more employees to provide five days of paid sick leave per year. City Council passed the bill last month.

An enforcement agency will monitor businesses to make sure they are abiding by the new law.

In the past, only businesses with 20 or more employees were required to provide five sick days. The mayor says that half a million more people will have paid sick leave when they need it.

The new law will take effect on April 1.
