Seems like a chicken and egg problem to me. I ask my developers to give me estimates and then my manager asks me why they're going to take so long (I trust their estimates, my manager is worried about meeting deliverables). There's no way to take that feedback back to the team without it adversely impacting the quality of their estimates going forward. I shield them as best as I can by intercepting requests before it gets to a member of my team, but stuff happens.
