If you think a tip for a server at your favorite restaurant is a gesture of recognition for good service, you're mistaken. 

“People think a tip is extra, to show gratitude for really good service, but it’s really not,” said Daisy Chung, executive director of the Restaurant Opportunities Center of New York, an advocacy group for restaurant workers. “Consumers should really know that they’re subsidizing workers’ wages, it’s not on top of it. You’re making up the difference for the fact that someone doesn’t make minimum wage.”

Today, nearly three-fourths of children live in homes where the adults who care for them work outside the home. Workers in jobs that have paid holidays and vacation time often cobble together those benefits in order to take care of a newborn or other family members. But low-wage workers whose employers don’t offer any paid leave, say the study’s authors, are at risk for falling out of the workforce and onto public assistance rolls when family members require their care.
