We've been trying. My entire team has mostly newcomers. We put in a lot of work, even worked through New Year's, and delivered a feature, but he never appreciates us, only the old timers. It's hard to get through to him.
“Look, I have done A, B, and C and judging from your response I feel like you don’t trust me. Is that accurate? Am I’m misinterpreting it? I expected X, Y, and Z would happen, but it didn’t. Can you please help me understand where the disconnect might be? I really would like to achieve X, Y, and Z. How can I get closer to that? Or is that not realistic?”
Maybe “delivering” a lot is not what he values. You need to find what that is. You might be using the wrong tool to get in his good graces.
