For example…I worked in a warehouse that had a janitorial and maintenance staff. The people that worked there were disgusting; they put their boogers on the walls in the bathroom and every year the maintenance guy had to scrape and paint the walls. My second year there when “painting day” came along, the maintenance guy was on vacation, so my boss told me to do it.
I said I was a chemical mixer and packer, not a janitor, and that painting restrooms was not in my list of job duties. My manager pulled out the “other duties as required” card, and I straight up told him that “I am not scraping fucking boogers off the walls in that shit hole.” He walked me to HR with the intent of firing me, and when he told HR that I was being insubordinate I explained that “other duties as required” did not mean doing the work of the janitorial staff and that while I was trained to handle several types hazardous materials, human waste was not one of them.
After explaining further, the restroom was closed, a cleaning and restoration company was called in clean, sanitize, and paint it, and we had a company-wide meeting outlining the proper use of bathroom equipment and facial tissue.
