I have grave suspicions whenever someone declares that change is going to cause some discomfort. I think they usually mean it will cause some discomfort for you. They have already made the changes they are going to, and now it is your turn.
At least, that's what I sometimes meant when I used to say such things. I don't say that anymore, having been on the receiving end of it too often. Others decide there will be changes. There's not necessarily anything wrong with that. They may be in positions of authority which allows or even requires it. But the reluctance of others to sign on quickly and happily is seen as a fault, not as a possible indicator that the change is not the right one. It's their change, of course it's the right one!
