We booked out summer holiday months ago. We'd been planning it for ages then got a letter from school with term dates and booked. It turns out they'd made a mistake and the date they said was the last day of the holidays was actually the first day of term.
We didn't realise for ages that the date had been corrected, in our minds all was fine. Every year we get back for holiday the day before the children start. Not that there was anything we could do about it anyway.
We filled in the holiday request form detailing what had happened, we have copies of the letter we based our booking on and referred to it. Our request came back with a terse Holidays are Not authorised in Term Time scrawled.
Part of me doesn't care too much, I assume they wouldn't have the audacity to try and send a fine in our direction
I'm fighting indignant feelings about never having wanted to extend our holiday into term time in the first place. We weren't really asking for permission but explaining why they wouldn't be back. Inside my emotions are stamping their feet wondering how can they not authorise it 
It would have been easier to have called them in sick by Skype in the middle of the ocean.
