Hmm good idea Mouse, I usually go there as its not far, but perhaps an hour with Turner and Constable is what I need.
Work stuff should hopefully be fleeting. Part of my role (also one of my objectives) is to deputise for my manager when she's not around as I'm on the highest grade. Someone else in the team takes issue with this as we all have the same job title (the different grades have widely different competencies though. Another part of my role is to proactively share my knowledge and she is happy for me to spend time showing her how to do things!
I had a chat with my boss yesterday evening about the situation, and she's got some ideas on how to approach it. Its the age old issue of having responsibility without the authority!
