I worked for a city for 15 years and can tell you there are people on the payroll that we didn’t know what they did. The administrator that oversaw my guys had a degree in hospitality and did know anything about water distribution.
Same here. Lots of useless city workers. Managers and supes got their wives and kids into jobs without requisite experience or brains. Lots of workers promoted up the chain to get rid of them from a group, and couldn't perform. When I was a junior-level programmer, a supervisor in a different group got my help in coding his programs, I don't know how he passed from junior to senior to supervisor; he eventually made it to a high level IT director of another department, without computer skills. When I was a senior systems expert working on building a 911 site, a high-paid manager kept offering to do errands for me, answering my phone, taking messages, getting me coffee, etc. I asked what he did, he said he didn't know. He was a friend of the mayor and got appointed into the department. That crap sickened me because I worked my butt off moving up the ladder over years. Many of the people were poor performers.
