There have been cases where an employee has been committing fraud, but it wasn't discovered for years because the person never took a day off and so was able to continually cover up their wrongdoing.
There's a decent discussion of it here on Stack Exchange: https://security.stackexchange.com/questions/107060/mandator...
It probably hasn't been ten years since my aunt's most recent husband got caught in that exact manner, and I'd frankly be surprised if it weren't still common, given that it appears to work.
(As a footnote, it was an interesting phenomenon to watch. "He's an accountant at some no-name company, and she sells Mary Kay. Where the hell are these Bahama vacations and the big house coming from? Mary Kay didn't give her that Cadillac, she bought it because no one buys Mary Kay. I dunno, must be up to their eyeballs in debt." Of course, looking back now it was friggin' obvious. His unfortunate solution to the hammer that was soon to fall on his head involved a 12 gauge shotgun.)
I don't know how to get established cities to follow such a program, but Taiwan seems to have figured it out. https://www.wsj.com/articles/taiwan-the-worlds-geniuses-of-g...

The most boring job I ever held was working in an office supply store. The people were boring, the customers were boring (and there weren't that many of them). I even worked in a warehouse on a packing line. That was pretty boring work, but the staff there found ways to amuse themselves and it was always busy. The days went by quickly.
Likewise, nobody is passionate about hauling my trash to the dump. (I have kids in diapers so my trash stinks) Nobody is passionate about cleaning septic systems. The jobs have to be done though.
All of the above jobs have something in common: well paid compared the the level of skill required. The people who do them have learned to do their job, and they have learned to find something else in life to enjoy.
