That's... interesting...
I haven't heard anything along those lines (and remember, I spent all evening reading an info pack from Disney full of rules and regulations!)
I can't imagine why something like that would happen...
I know a friend of mine who's working Main Street USA QSF&B at the mo is contemplating work for Disney (As am I!), and she obviously hasnt been told this.
Perhaps he meant if your contract is terminated (i.e you get fired), Disney wont re-employ you?
