Change In Schedule For School Board Meeting?

It seems that the regular scheduled School Board Meeting set for 10 June has been changed to Tuesday night 8 June at 5PM. The thing that makes this an usual change in schedule is that it was changed during a work session where there is not supposed to be any decisions made. It also coincides with the fact that the School Director is facing an ethics charge scheduled to be discussed. Also a conflict exist that would have prevented Mrs Norman from being there, Mr. Jackson's most ardent supporter, it's odd that such changes are not made for other board members. Where has this meeting been announced and posted where the general public could view it, in accordance with County policy and state law? Allen Barrett
