Most has been said about staff and pupils not being able to get in safely or to have a safe, comfortable productive environment when they're there, but any teacher will tell you that trying to teach when there's a good amount of snow outside is a nightmare! The presence of a snow is totally distracting, they are hyper before break and soaking after break! I recall as a student the coach for Teaching Practice not coming so I dashed into town, caught the train, slogged through two feet of snow up to the school, got there at break and was told by the Caretaker, Yer mad b@@@@r, we're closed. Bless today's messaging, no such thing then.
