Consider a medium sized research group, say a dozen people or more. It's typical in certain fields to have a project manager that looks after finances and other admin tasks. Sometimes the person will have a background in that field, sometimes no relevant academic experience.
I've come across some project managers who consider themselves very important and influential. I'm just wondering how much decision making power they actually have since the head academic ultimately calls the shots? Is it appropriate to appeal to the head academic if you disagree with the project manager?
