Years ago, I worked part-time in the admitting department (ER and office) of a local children's hospital. My co-worker's husband was the ward clerk in the ER. She was quite the pill, but he was even more so. He was a complete, obnoxious know-it-all - he had no medical training, but would triage the patients coming in (a nurse's job only) and give out medical information to the parents. He would tell us how to do our job and come into our section, turn up our radio to full-blast and leave it that way when we were in the middle of registering someone and couldn't leap up to turn it off. How exactly he got away with this (and how the hospital didn't get sued), I don't know. He was responsible for scheduling though and would kiss-up to all the nurses there by giving them whatever shifts they wanted, so we figured that some people were turning a blind eye to the goings on.
After he had been there for quite a few years, we heard whispers that he had a second job. No big deal, right? Wrong. Turns out that job#2's shift started at noon. Well, job#1's shift at the hospital didn't end until 3:30 PM, so he would show up for the first part of his shift and then leave half-way through, but he was still drawing a full-time salary.
All that came to an abrupt end when a new manager was hired and was going through the budget, etc... for the ER and wondered where the head ward clerk was in the afternoons. She lowered the boom and he got fired. He's lucky he didn't get charged for all the money he'd been paid while not working there!
