I worked as a lifeguard for a fairly large city. The Parks and Rec department had a director, assistant director, and then an aquatics director under the other 2.
We had just built a new aquatic center so the P & R director hired an independent consultant and a new aquatics director. She was new to the pool industry so didn't have much knowledge of how to handle a pool.
The consultant was the biggest idiot I'd ever met. The policies he started went against everything we are taught as lifeguards and even bordered on illegal. For instance, he became convinced that children were purposefully defecating in the pool (the children's pool for kids 12 and under, of course there is going to be poop in the pool). so instead of clearing the pool and shocking it with chemicals, he told us to keep people away from that area and have a manager scoop it out.
About halfway through the summer, the aquatics director made a decision (that she was hired to make) at the advice of the more experience guards but it went against the consultant. He had her fired for "insubordination."
I left after that summer.
