This is absolutely true. I spent years int he industry and if you took time off because you were sick you may be fired this goes for the front of the house or the back. I remember one time I worked at a “Italian” style corporate restaurant and I was terribly sick. I had severe bronchitis which I ended up in the ER with the night after my shift. I told my manager that I was running a fever (about 102) and I could hardly breath and his response was “Make sure you go to the doctor before you come in tomorrow” and he walked away. You are not allowed to be sick in that industry, ever. If customers knew how often the people who handle and serve their food are sick and spreading germs they would probably not go out to eat.
In an office job if you’re sick the powers at be want you to stay home. If someone tries to gut it out they are invariably told over and over again to go home and get some rest.
This is not the case in the restaurant industry. You’d think that GMs would want folks to stay home rather than cough on customers, food, or other servers. Sanitation should be key…except when you’re sick and haven’t found someone to cover your shift!
