So many mistakes made, all of them in a large firm where I was employed as a secretary - cheques / emails / letters sent to the wrong people... documents lost.
To be fair, I had a horrible, aggressive boss who was demanding and impatient. He overloaded me with work and would get angry if I asked him to clarify one of his instructions - he often gave me vague instructions.
On one occasion, he asked me to send a sensitive document to "everybody" and got impatient and snappy when I asked him to confirm that he meant "everybody".
So, I emailed the doc to "All Staff".
Boss comes over, screaming with rage, because he actually meant the document to go to everyone in his department and not the whole company.
This sort of thing seemed to happen on a daily basis. I was so intimidated by this man that there were times when I literally lost the ability to speak.
I resigned after six months. It was a horrible company and I wasn't the only one who suffered.
This happened almost twenty years ago and I still shudder at the memory.
