I have a chronic health condition that my boss is aware of. I was paid late and therefore unable to refill my medication on time, and although I managed to work for a few days without it, yesterday it finally caught up to me and I couldn't breathe. I called in sick and explained the situation. Despite being transparent about my health in the past, my boss never once mentioned a doctor's note for absences. However, yesterday evening she sent me a text saying to “remember to provide a medical note explaining my absence.” I know doctor's notes are often needed for multiple consecutive sick days, but I only called in for the day. Obviously I don't have a doctor's note and the only option I have is to send her a photo of the medication I take and the bill of the prescription I filled yesterday, but that feels like an invasion of privacy.
This is a minimum wage job. I don't mind the work itself but every day I'm humiliated and belittled in front of my coworkers by my supervisor (not the boss). Being paid late and asked to provide proof of a chronic illness has brought me to a breaking point and I'm tempted to quit. Am I overreacting to the situation?
