Annual performance reviews are coming up and a senior manager whom I work keeps warning me informally that I need to get more things done and make things happen and that recently I haven't.

I am an assistant manager of another team and my role is more of a spokesperson for that team rather than a decision-maker. I also help with basic coordination and filtering requests. The team I represent has had an enormous amount of requests that it cannot deliver simply because - in most cases - it doesn't even have the resources to meet that amount.

My boss knows this and tells me to keep those requests away. The external bosses tell me to do more or that I am putting my job on the line.

Is it my fault if we don't have resources, I cannot decide on resources and I am doing exactly what I am told to do by my boss + how can I ensure that my performance review is not tainted by these warnings over which I have no control?
