How very unprofessional of the strata manager.
The strata managers job is to assist the owners, Sometimes the recommendations of the strata manager are knocked back by the owners. Thats life.
A professional strata manager will just take it on.
Maybe in this case the strata manager is considering their “liability”
The strata act absolves the strata manager of the decisions of the owners. It’s their decision and the owners are accountable for it.
A good strata manager would make a note in the meeting minutes that the recommendation of the SM was rejected and that the owners voted an amended motion
And in my opinion, a large part of a SMs job is to manage the “personal” part . That means managing peole and the various tribes and factions that exist. But never to intervene
