So I volunteered to help sell drinks this morning up at the high school to raise some funds for the booster club. My son is starting high school and I am new, so I don't want to get off on the wrong foot...but I was told to show up at 9 and arrived a little early, so I called my contact to ask if he was there yet because, from past experience in middle school, I know he tends to run late. Well, he wasn't there and he told me that they really didn't need my help after all. In fact, he probably wasn't going to be there either.
Okay, I'm happy to volunteer. I LOVE to volunteer, but this kind of crap really makes me mad. I have a very flexible work schedule but it's been very slow lately and I turned down some work for today because I had already made this commitment. Not cool to waste my time like this. So like I said, I'm the new parent and I really don't want to get off to a bad start, but if this happens again, I am not going to be volunteering for them.
So my question: Should I send an email and tell them about my experience this morning and ask that they be more considerate of my time in the future, or should I just let it go this time and only mention it if it happens again? Or some other option?
