Hello Ray,
From my experience your last comment is distinctly unfair. I have a close relationship with a number of schools, and I can honestly say that the vast majority of teachers and other school staff work beyond the call of duty.
I am a governor at two local schools, a primary and a secondary. The primary has remained open, and all the staff have made it in - and one member has to travel 35 miles!. The majority of children have been in, because living quite locally to the school they can be walked in.
The secondary has been closed, but out of a staff of 150, only ten did not make it to school. I am not aware of the reasons, it may not have been the weather. The reason the school has been closed, is two fold. Firstly it is difficult to keep the grounds and paths clear and safe to walk on due to the snow fall and underlying ice, but also the school has a very large catchment area, and the majority of children are bussed on specially booked coaches. The snow conditions across the catchment area has been very variable, from 6 inches to about 1 inch.
The bus companies have had concerns about travelling, and whilst it may be relatively easy in the morning, the conditions can change significantly by the afternoon.
Generally there has been an increase in the number of parents who bring claims of negligence against schools, for what ever reason (one of them may be unsafe footpaths etc). Even if it is proved the school has done every thing it reasonably can and is thus not liable, the costs of defending such cases still falls on the school's budget, and such cases are often quite expensive.
