I think it might actually have been getting coal to the gas works or oil to the power stations that was the issue but in the mid 70s I remember the primary school I worked in closing to the children - presumably because we couldn't heat it or provide dinners. We always referred to it afterwards as "the gas strike". We had to go in and did (a bit) of work in the staff room. I think there were days if we turned up and signed in we were then allowed to go home. On some days we brought in the children with learning difficulties and did some small group teaching in the one room that we could heat. I haven't made this up. Then there was the time under Edward Heath when, for a while, our salaries went up each month. I'm not making that up either. But you know that - this is the Retirement forum after all.
