I'm having that trouble in church, too. I'm supposedly on the Sunday School Board, but the superintendent (3 months in a row) has "forgotten" to let me know when the meetings are. Last year I had to resign because she kept planning them on days I was out of town and I didn't think it was fair to the church to miss the meetings.
This year, I was elected and told I would have more input into the meeting dates. Now I don't even know when they are. Last week I even asked her husband when it was and he said he didn't know (it was later that same afternoon).
She did tell me when the next one is, so maybe it is just an "oversight".
