I am so pissed off with DS's school. I thought that this year they would stop their nonsense of finishing just after lunch on the last day of each term and registering them in for the afternoon but requiring you to pick them up early. 
In previous years they did this on the last day of every term and I assumed that the new "tightening" up of rules re taking DC out of school would mean they wouldn't dare do it this year...
They mention earlier in the year on the calendar a picnic at 12 noon that parents are welcome too and then start gradually drip feeding into the newsletters that you are welcome to take them home after the picnic and then BOOM today - dates for July:
Wednesday 23rd Picnic 12 noon BREAK UP 1:15pm
This means extra time off work for me.

Considering the attendance was matched against 2 half weeks and about 4 full weeks then yes it did come out at
