Back when I still worked in a cubicle farm, I had a boss that was that way -- well, why can't you come in, we've got deadlines, we're going to lose a contract, yada yada, if you're throwing up, take some pepto, if you've got the 'rhea, take some imodium.
I'm like the OP, it's rare that I call in, and if I do, believe me, I'm sick. I called this jerk to tell him I'm sick on a Saturday morning, and I'm coughing and gagging like I've got whooping cough. He tells me to take a cold med and come on in. About that time, I cough up something and go...."oh, that ain't good, I gotta call the doc, bye." I call my doc, who tells me to meet him at the ER. Turns out I had walking pneumonia. They're taking xrays, giving me a neb treatment, etc., and the doc keeps looking at my purse, which is ringing off the hook. I pull out my cellphone, and I'm really not able to talk. I tell Dr. A it's my boss, then go back to gagging and coughing.
Dr. A introduces himself, listens about 30 seconds, and then proceeds to rip my boss a new one. I wish I was able to remember it word for word, but I remember it being priceless, and apparently the idiot told the doc to give me a cold pill or something and send me in, because I do remember him yelling, "and where did you go to medical school? And what is your DEA number, because you sound like you're trying to tell me how to practice medicine? She is sick, she is being admitted, and I don't want you to call her again until I have discharged this young woman." Dr. A was so mad, he asked me how many days off I wanted so I could get a vacation from this moron.
