Please fire me. I had to call in sick to work today (I have bronchitis & Pneumonia), and my supervisor replied that I needed to give them two hours advance notice. I called at 8:30 AM, my shift starts at 9:30 AM, and my supervisor doesn’t arrive until 8:00 AM. I’m sorry, was I supposed to call at 7:30 in the morning to a location where no one will pick up the phone?
