My sister called in sick for me one day- I had food poisoning.
This was many many years ago, before cellphones and when older houses -as ours was - usually had one phone and they were hardwired so you couldn't move them from room to room. I was upstairs; the phone was downstairs.
The boss intimated that food poisoning was maybe a not good excuse. My sister -who is ruthless when she has to be- pointed out that constant vomiting is not what customers at a fast food restaurant want to see. They got into it further and the boss finally agreed that I was calling in. Then she told my sister that I should be the one calling in. Thoroughly fed up my sister snapped "she would if she could make it downstairs to the phone without throwing up!"
Thus my passed my first day with a new store manager. Needless to say she never warmed up to me.
I've been fired from a sum total of one job. I was working at the alumni center at college and got shingles. I couldn't leave the dorm room except to go to the ER for pain. I called in the first day after I got diagnosed and spoke with a student supervisor. I told them that I was contagious and couldn't come in to work, that I would provide them with a doctor's note upon my return. Not a problem, I was told.
My evening shift comes, and I get a phone call. I'm passed out from pain and miss it. Check my voicemail, it's my manager wanting to know where I am. I call her back and repeat the conversation I had with the student supervisor earlier that afternoon. "Oh, well, she never mentioned it or wrote a note for me. I'm going to have to count this as an unexcused absence."
Okay, fine, I tell her again (second time I've told her, third time I've told someone in a supervisory position working there) that I will not be in until the doctor clears me as non-contagious and I can actually sit up and speak without extreme pain. I'm told that will be satisfactory, as long as I can produce a doctor's note when I come back. Okay, great. Pass out again.
The next day I had a morning shift (weird for a call center, but I did work with mailings as well). Third manager calls me, higher than the other two, wondering where I am. I explain both of the conversations I'd had the previous day, explain a fourth time that I am contagious, cannot come in to work and will provide a doctor's note when I return. Third manager has no notes from previous two supervisors, and since I didn't call before my shift and let her know, this would be an unexcused absence, but both absences will be forgiven when I return with a doctor's note.
The next evening, I had another shift. The second manager called me again wondering where I was. As though shingles clears up over two days. I explain to her a third time that I cannot come in. I am sick. I will let them know when the doctor clears me for work again.
The next day I was let go because of multiple unexcused absences and refusal to come in to work when told to. At that point I was too sick to fight it, so I waited until I healed and found another job.
