Money Over Health
We don’t have to be the ones to tell you that you shouldn’t come to work if you’re sick. Worst-case scenario, you sneeze all over your customers’ food and cause everyone to die of pneumonia. Thankfully, that didn’t happen in this story, but that doesn’t mean someone didn’t get fired.
The boss was mad at the OP for requesting a few days off to feel better. It wasn’t good enough that one employee was sick, but the boss wanted everyone who handled food to fall ill, as well. Employers should know that it’s cheaper to retain old employees than it is to hire and train new ones.
