Board meeting

I am a Non Exec director for a local organisation. Today was my second meeting.  It did not go well. 

The meeting start time was 8:30 am, end time was not stated. Meeting started at 9 am since some people were late. Then general talk started, very little to do with the agenda. Then agenda items were covered. Sufficient time was not spent on this!

I left the meeting at 10:15 since I had another meeting at 11 am. After my meeting I emailed the CEO outlining my concerns:

1) Not sticking to the agenda

2) No end time

3) Not sufficient time was spent on agenda items

I wonder how long they will keep me on as Non Exec?
