BadNewsRef wroteThis confused me: "It doesn't work the other way around, our high school assigner can't see our Catholic middle school assignments"
My high school assigner hasn't asked us to change our profile to allow that. My Catholic middle school assigner has a great relationship with my high school assigner, they both know that high school assignments take a higher priority over Catholic middle school assignments, even to the point of getting a last minute high school game a few hours before game time. If you already have a middle school assignment, call the middle school assigner, and go to the high school game.
Since I don't work NCAA games, I have no idea how my high school assigner prevents conflicts with NCAA assignments, however, I do know that he considers NCAA assignments to take a higher priority over high school assignments, in terms of closing out dates, turnbacks (no fines), etc.
