Fifty-one percent of food workers — who do everything from grow and process food to cook and serve it — said they "always" or "frequently" go to work when they're sick, according to the results of a survey released Monday. An additional 38 percent said they go to work sick "sometimes." [...] But it's not as if these sick food workers are careless. Nine out of 10 workers polled in the new survey said they feel responsible for the safety and well-being of their customers. Yet about 45 percent said they go to work sick because they "can't afford to lose pay." And about 46 percent said they do it because they "don't want to let co-workers down."

"One of the most egregious examples that I describe in the book is a worker at a Fayetteville, N.C., Olive Garden [who] was forced to work with hepatitis A because [Olive Garden] doesn't have an earned sick leave policy," [Saru] Jayaraman says. As a result, Jayaraman says, 3,000 people had to be tested for hepatitis A at the Cumberland County, N.C., health department.

Paid sick leave isn't just the right thing to do for people who currently face the choice of going to work sick, or going without pay. It's a public health issue That means that customers are exposed to those sick workers' illnesses. And that, in turn, can be a serious issue:Most cases aren't that dramatic, of course, but norovirus is often spread by food workers, and you really don't want norovirus . Yet somehow Republican morality says that these workers in one of the lowest-paying industries should stay home to protect the rest of us while being denied basic protections themselves, and risking their ability to pay the bills and put food on the table for every day they stay home sick.

Paid sick leave is gaining momentum in the United States, with four states—Connecticut, Oregon, California, and Massachusetts—now having laws requiring it for most workers. But it will never be federal law as long as Republicans have the ability to block it.
