Did you know that there is such a thing as sick-day guilt? It’s when your body screams rest but you can’t make yourself call in sick for the day. This feeling is triggered for different reasons such as not wanting their employer to think they can’t cope with the job or feeling bad for asking a colleague to cover for them.

But taking a legitimate sick day is nothing to feel bad about. After all, employees aren’t robots and we need a day off to restore our energy every once and awhile. The next time you’re feeling sick and need a day or two off from work or school, I’ve written down more than a hundred sick day email samples you can send to a boss or professor to let them know you’re feeling under the weather.
