Don't want to give too much away as it will out me. I am one of the head's of a department at work. I met with another department to get some input on things we need to do before data transfer and was planning to cascade this information to my team on Friday morning at our weekly meeting.
One of the ladies who works in my team found out I had this meeting without her (she deals with the data everyday but is not head of the department) and was not happy. I explained that I was going to share the information on Friday and she said that she wants to hear it direct from the department and will find them herself to ask.
At the time all I could think about was how I had upset her but having talked it through with my dp, it's been pointed out that actually what she said was rude to me as she clearly doesn't trust me to pass on the information. 
I felt I acted appropriately as i have overall responsibility for all data and transfers and am still planning to share with the whole team Friday.
AIBU? Been worrying about it all evening as she can be a piece of work if you get on the wrong side of her.
