I think cattle are a lot like kids. they know what they can get away with, with their parents. Mine used to just walk around me when going to the squeeze. They never got excited, just pushed me out of the way. If I bring in help, I keep them outside the pens. All they need to do is stay behind them.
I guess the best think I have done is give them a treat about one time a month and allow them to exit the pens only by the squeeze.
As far as your arm goes, maybe there is a plus side of no breeding season.
