Operators kicking each other in a public channel just undermines their authority, especially if arguing ensues in the open. Try to resolve problems in private, or maybe just don't give every staffer an op. It looks childish no matter how you slice it. If you're prepared to give ops to another, then you trust them and let them do what they please.
Of course the question remains why would you even want to ban anybody? Bans don't do anything. If folks are annoying, you put the channel on moderate (+m). Regulars should be voiced, anyone else can just ask for it in PM if they want to chat, and that's it. If regulars go berserk, you take away their voice, you piss them off to no end.
