Similarly, we had an actor who was asked to roller skate on stage for a show break her wrist falling while practicing her roller skating on her own time, initiative and volition. On the one hand, it was for the show. On the other hand, no one had suggested she practice roller skating near the rehearsal venue (far away from her home), after a long day of rehearsing and in a big, crowded, public venue where injuries are far more likely to occur. Fortunately for the theater, she was not considered a worker's comp charge (tho, I suppose, a good lawyer cd have argued the other way had it gone that far).
