"We had a sysadmin who would come to work and run his real estate business from his desk while he was supposed to be working. The whole time coughing and sneezing and sniffling constantly. We called him “Itchy”. He would also call friends and family and have hours long conversations with them while we all had to listen.
He picked up the nickname “Thanksgiving dinner guy” for using the break room (full kitchen) to cook entire meals that wouldn’t be out of place at a family gathering. One of the offices in another wing had a sheet by the door for people to log when they saw him and what he was cooking that day.
He didn’t like any of us (the feeling was mutual) and left books like “J#rks at work.” on his desk.
When he finally got fired, they found out he never did any of his sysadmin work. No backups, no password changes, no log monitoring."
