The interesting thing to think about is not just in regards to your own managers. This extends out to clients, partners, customers, etc. When they are allowed to constantly shift the goalposts and your response to your employees on the front lines of those relationships is “eh, you know how they are”, consider the fact that you are not keeping them safe. It’s not just an irritation, it’s creating an environment that is not psychologically safe for them. It is doing harm.
This gets old, and as the quote above says, it contributes to a loss of trust and cynicism. It might also lead to a ton of burnout too.
