From Infoshop.Org. I worked in bars and restaurants for fifteen years. This is standard practice in the “food service” industry.
It may come as a surprise to those who have never worked in the food industry to hear that not only Jimmy John’s sandwiches, but also the pizzas, salads, burgers and burritos that are consumed in many American restaurants often have a few secret ingredients: cold, flu and other germs. There is a simple reason for this. Jimmy John’s and many other fast food restaurants do not allow workers to take sick days. Management pressures sick workers to find a replacement or come to work.
