No way you can put a "median" on these jobs without physical location of where the job is.
A few years ago when I was living in New York city, the leftist sewer hole of the east coast, they did a story on NYC school janitors that they average $11K a year and with overtime they were making close to $200k. One guy was made $280K in a year. For mopping floors and taking out garbage! LOL! Look at their city council, part time job and they make $150K a year and they do absolutely nothing except promote commie ideals and celebrate commie spies.
