Why are parents relying on the district to make sure we are represented on district committees?

The Budget Review Committee is supposed to have two parent representatives but I was the only parent in attendance at the June 16th meeting. I was unable to attend a previous meeting due to work obligations so I understand why another parent might not have been able to make it. It's a shame the district doesn't have alternates lined up to make sure parents are fully represented. In my opinion, parents are the ones who should be responsible for selecting representatives to district committees and should also be responsible for having alternates available to fill in.
