Lots of people want to be ski instructors at the Okemo Mountain Resort. Nobody gets rich doing it, but there are perks, including a free season pass and half-price meals at the Sitting Bull Bar & Lounge. Named one of the best places to work in Vermont for five years running, Okemo employs more than 400 instructors, who run “a really wide gamut,” according to Chris Saylor, the school’s director. So when a 74-year-old retiree applied for the gig a few years back, Saylor didn’t think much of it. The man skied well and had a friendly, patient demeanor. He also seemed to embody the company’s core values: safety, service, sustainability and teamwork.
