Maybe things are different in WI, but I don't think that they hire minimum wage employees. One of my close friends who used to work here is now at our biggest shelter. She makes a whole heck of a lot more money than I do and mostly spends the day doing euths.
As far as people freaking out about dead bodies, you'd be surprised. I get 'what happens to the body?' pretty frequently, and people get genuinely upset about them being in a freezer. Not sure what they expect.
