I'm moving into my second year as team lead for a small team. We work in a small Branch of a big company. We are all physically close and often cross paths and see what each other are doing, including crossing paths with my superior--who often acts casually as the team lead as well. (Yes, come to think of it this is a quite a pain and constant weight over the situation)
My team has mastered their main duties and have politely relayed to me that they are ready for an increased task load. They are interested in more variety of work, and in working with customers more. I agree with my team, and I intend to use my position to make this a reality for them. However, my superior is not the easiest person to convince for creative change. This person is not readily open or approachable on doing new things. They have a brusque style where they tend to incline towards quick responses in the negative. This makes it difficult to even get a conversation going as they fall into the conclusion so quickly.
How can I get through to a person like this?
