Regardless as to whether or not you agree with my interpretation of the law, our legal system is founded on the principle of "innocent until proven guilty." The burden of proof lies in the accuser. If someone claims that you are participating in an "illegal work stoppage" they must prove their claim. You do not have to prove that you were not breaking the law, they must prove you were. How will they prove you were not sick?
Do not give in to the fear mongering. District policy does not require a doctor's note if you are absent for one day. If asked, you were sick. End of story.
I will post again tonight.
