Yes. Swim meets are run by parents so each parent is expected to sign up for a volunteer shift at the swim meets your child is competing in. You are there anyway so you may as well help out. The volunteer shifts are usually short (2 hours or so). If you have further questions about this, please ask.
At our home meet at the end of June/early July, the volunteer help needed is much greater than at any other meet all season. We will be asking all parents to come and help out – even if your child will not be competing. Shifts will be assigned if there are not enough people signing up ahead of time.
