Dora, sounds like my county! Sussex by the sea.
I'm in Sussex, too, Eyes. We're 300' above sea level, just off a very steep hill. We can have 3" of snow and a lethally slippery, icy road but it will be fine down by the shop, which is only about 300 yards away. It's like having our own personal microclimate.
It's only a mile to where I work, but I'm not bloody walking it. I broke my wrist slipping over on the way to work in snow 10 years ago and, despite surgery a year or so later, it'll never be pain-free or have the full range of movement. But I have brought some work home, so I can log on from home and get on with it, if the promised snow arrives and lasts till morning.
The employer's snow policy is, if you can't get in safely, work from home if your manager agrees, or from the nearest office or other establishment that you can get to safely. DP's employer has an almost identical policy.
I think expecting teachers to risk accidents or being stuck on some snowy road, like those poor buggers on Bodmin Moor, is daft. Teens should be able to revise on their own, and topics missed caught up on later. Them being off isn't a matter of life and death.
