Listen to the objectors
Of course things are much easier and more pleasant if everyone just says "Yes" to what management proposes. Surrounding yourself with agreeing bobble heads is a sure path to failure.
Years ago I was in a choir and as the youngest member was quickly voted onto the board to give a fresh perspective. One board member was almost always against everything and he went to lengths to explain his objections. At first, I though he is just miserable and annoying, but when it turned out that he was right on a few occasions my view changed. It completely flipped when his opposition saved our club from a substantial financial loss.
I have no idea if he always disliked the ideas, but his attitude forced everyone else to think over our decisions and revise them as needed. He was a pain to work with, but overall one of the biggest contributors and delivering great value.
No matter what the motives are, listen to the objectors. They have a different view of things and they challenge leadership who otherwise might think they are infallible. When convincing the objectors that their view is not accurate they also tend to become the biggest advocates for the proposed change. Objectors are often the biggest friends you have, don't fire them!
