The problem is that teachers generally don’t live next door to the school (you would have to be nuts to live beside your pupils) and do have to leave pretty early to get in for 8am or whenever.
My wife drives to Livingston every day. She got up as usual, all set to go. I cleared the car for her just before 7am, and thankfully she got a text just in time to say it was closed (last time it was closed she was almost at the start of the M8, having driven 8 miles or so). I am really glad she is off actually. I don’t fancy the idea of her getting stuck on the M8 on her own all day, or some idiot driving too quickly and running into the back of my shiny car at the lights!
The roads in Edinburgh don’t seem too bad, but at 7am they are a lot worse, and I guess that West Edinburgh / West Lothian is a lot worse still (my parents reckon they have 12″ of fluffy stuff by Balerno).
If only 50% of teachers make it in, you have a major health and safety issue for the council. Do you have enough teachers to adequately monitor the kids? What if there is a fire?
