More than half of private sector workers in the leisure and hospitality industries, which tend to have a lot of face-to-face time with the public at places like restaurants and hotels, don’t have access to paid sick leave.

“We know that when people go in sick they infect other people and when we talk about lower-wage workers in the service sector who are handling food without paid sick leave and other benefits like health insurance, that is really dangerous and a public health concern,” said C. Nicole Mason, president and CEO of the Institute for Women’s Policy Research.

In addition, nearly 60% of part-time workers don’t get paid sick leave, according to the Labor Department.

An executive order signed by former President Barack Obama requires federal government contractors to offer paid sick leave. And some state and local governments have passed laws that require companies to offer paid sick leave.

But some workers may still be hesitant to take advantage.
