From the duh files:

A nationwide survey found out that most of the food workers in the U.S. still report for work even when sick.

Based on a poll conducted by the Center for Research and Public Policy for Alchemy Systems, the majority of food industry workers are most likely to show up for work even when sick with illnesses that will most likely make their customers ill as well.

Survey findings revealed that 51 percent of food workers report that they “always” or “frequently” report to work even while sick. These findings were more or less the same as the last time these surveys were conducted, and are part of a larger study to determine safety issues on major food and food production industries.
