I know that search and rescue organizations have been changing their policies on billing for rescues, usually from not charging for their services to charging for them. But that's not what we're talking about; we're talking about employees performing their assigned duties,.
If the resort paid out for outside services and made an insurance claim, and their insurance company finds the person rescued was at fault, it's the resort's insurance company that'll sue the guy and get compensated.
But the resort employees did this rescue in the regular course of their employment, and if the resort decides to eat costs like helicopters, overtime, and employee good will instead of making an insurance claim, there's no one to go after the guy for the cost of the rescue.
Dontcha hate having a lawyer in your midst?
