Under-appreciated by their employers. Underpaid.
Job has a great office, though.
As part of my professional life I used to help outdoor and ski brands, and ski areas interpret, and put into action data on brand share, consumer demographics, market segmentation studies, etc.
As a retired guy I instruct once in a while, and when I walk into a resort I see spreadsheets, traffic flow, and process inefficiencies. Part of that is ski school.
Instructors spend the most time of any resort employee, with guests. They are an area's greatest asset. They are an area's best chance to put their best foot forwards. Yet, often times, they are treated like a nuisance by ownership / management.
