I help out when I can but having one child in primary school (and two others under 5) is a logistical nightmare.
I work three days a week and spend countless hours organising my work diary so I can be at the school for:
Parents lunch day
Class assembly
Sports day
Year group trips
Parents forum
Christmas carol concert
Early finishes
Insert other stuff that I get about a weeks notice for
Then there the cake sales at least once a month, endless fundraisers, but a book for the school library, wear green socks for house teams day, sport relief, comic relief, friendship day, world book day; operation Christmas child; harvest festival donation, school fund, mathletics app etc.
While I was on maternity leave I also helped out in the class once a week.
Then add in homework and daily reading, extra curricular activities (which also include me volunteering at dance shows for a whole weekend).
A million birthday parties and reciprocating play dates are also on my calendar.
My middle child joins the school this year so the logistics will double.
My husband travels for work/works late and so it's not always possible to have alternative childcare, and we already pay out a small fortune in childcare.
I would also rather just pay (even more) money to the school than volunteer because there just aren't enough hours in the day.
And yes, all discussions are at 3pm on a Thursday when I'm working. Surely a 5pm meeting would work and I could potentially leave work an hour earlier for it!
