Most teachers are well aware that we are one of the few professions (if not the only) where you have to do more work if you call in sick then if you were to just go to work and struggle through it. It doesn’t seem right that when we are feeling terrible we need to try and create or write up a coherent lesson plan that anyone could implement while taking our place in the classroom. Even if we want to just take a day off, we need to prepare ahead of time and come up with a plan-of-attack for our substitute. It’s unfair, but it is also the way things are. This is what I do to make my life easier when I am out of the classroom.
