What’s in the collective best interest may not match with what’s in the individual best interest. Perhaps unions are more likely to be in the self interest of the below average employees, the ones with no negotiating power. The best school teachers are almost certainly being held back by their unions and the worst ones are getting a free pass. When I worked at a unionized place I was blocked from an opportunity my employer offered me because it was better than what the standard negotiated terms were.

The alternative isn't what is in your best interest, but what is in your boss's best interest
You can fall ill or need working accommodations regardless of whether you are above or below average.
For me, the only one who has ever used the standard terms as a floor has been the employer. The union has always backed me up when I wanted higher pay.
I'll give an example. I've had managers switched on me, and they've then said my salary has to be reduced because it's higher than the median. The organisation I work for also has a salary policy where every level you advance, your "personal additional percentage" is cut. This eventually reduces everyone to the same, lower level. This is the employer, not the union.
The union, otoh, backed me up when I wanted to keep my existing extra percentage.
The rising tide lifts all boats.
Denying people agency and power in their negotiation by claiming they are "not as good as someone else" is antithetical to the struggle of labor - work deserves to be compensated fairly.

Your union blocked this because your employer was trying to break your unions negotiating power by separating your interests from the collective workforce. If people who are sympathetic to management and accept that they will be compensated greater by acting against the interests of the labor union, the union should block these promotions. If you don't want to protect your coworkers by negotiating with them, then you must be interested in exploiting them by negotiating against them. Labor is a zero sum game.
