The mountain where I teach PT, we get up to 2 one hour paid clinics per week. There must be at least 5 instructors in the group to call it a clinic. I'm sure we are covered WC during a clinic because we are getting paid. There was a short time after one of our instructors tried to claim WC injury after doing something stupid in a ski school jacket while free skiing and seriously injuring his shoulder that the ski school didn't let us free ski in our jackets. That didn't last long. Now we are back to skiing free skiing in our jackets. YM
My question, why would you want to free ski in your uniform? The uniform is far more of a burden than anything else, IMO. You are instantly identifiable as a mountain employee, which means your code of conduct has to be consistent with the mountain employee code. I don't know about you, but I have been known to employ some salty language at times while i'm skiing, especially when with other instructor friends. Also, I may at times bend some rules on the mountain. You know, the ones that are in place for the average joe to not do something stupid, but which someone on the mountain who knows their stuff can pull off without risk. If I'm in my uni jacket, I can't do that. Further, when you're in uniform, you are opening yourself up to having people approach you to ask questions, seek help, etc. At my mountain, if you're approached by a guest while in jacket, you help that guest through their whole issue, unless you're actively engaged with another task, like a class.
I just don's see the advantage to skiing in uniform. Much better to be another anonymous face in the crowd.
