I re-read my post and I sounded a bit flippent. That wasn't my intention. Yes the letter made some good points BUT who do you think will get the blame for students not achieving the best grades if they lose 3 months plus of education(meaning classroom time) over their school career due to Ramadan?
I stress again the missed lessons can never be repeated, or if they are it will be at the expense of other vital areas of the curriculum.

I dont think Iftar is an issue because their partners are home at the earlier time so they can do that. And to be honest I haven't heard any of the Muslim teachers complain.

In an ideal world this issue would not arise, the school is just trying to come to the most benificial solution for the students. The school after all is there for them not the staff.

I don't go to mythical places with strange men.
