In addition to handling luggage, I would empty out plane lavatories, top off the drinking water and run the mail to the airport postal facility. NEVER trust the drinking water on a plane by the way.
As for the luggage, I saw all sorts of shenanigans like what these guys did. Once the luggage got into the hold, some workers would rifle through luggage that was not locked, looking for valuables. I don't think they can get away with that these days because everything is on camera. Even the cargo holds now have cameras.

Reno TSA inspected my checked luggage and snagged a few hundred dollars worth of electronics.
TSA left me a nice note letting me know that my luggage was inspected for customer safety.
I watched some airport maintenance guys adjust a conveyor diverter by removing the side rail so the could see how far it could launch a bag.
