At least here in (highly unionized) Finland unions set only the floor on the wages and other working conditions, and especially in white collar jobs practically everyone is paid above the floor. Some, mostly public sector, contracts have union negotiated "wage tables" suggesting pay based on position and individual performance, but similar exist in almost all large organizations. And the unions don't care if someone is paid more than this, and at the moment they wouldn't even know, because individual pay isn't public information.
