All the park’s a stage
Disney employees aren’t technically “employees”—they’re “Cast Members.” And no, not just the ones who play actual Disney characters. Every employee in the park, whether they operate rides, serve food, or actually put on a show, is a “Cast Member.” The idea is that the entire Disney park itself is a “stage.” Even Disney’s career website talks about the “unique opportunities available to Cast Members.”
Everything is Disney
And what’s the most important thing a Cast Member has to do? Stay in character, of course. If you’re playing a Disney character, that character’s world becomes your world. You’re not allowed to make references to any pop culture that exists outside of the Disney universe. From the moment you don the costume to the moment you take it off, you can’t talk about anything that Snow White, Peter Pan, or whomever you’re playing wouldn’t know about—whether that’s the latest iPhone or the Harry Potter park just across Orlando.
