Thought provoking. I was part of the 'squaddie' task force that stood in in the first fireman's strike.
Although all of us had rudimentary firefighting training, nothing could prepare us for what we came across, some couldn't hack it at all while others found they could, indeed some went on to join the fire service after completing their time in the mob as a direct result of that strike.
I hasten to add, this was the strike in 1977 which went on a lot longer that the then government would come to realise (and us, we were told only pack a weekend worth of civvies!).
I was in Brum from the November until the following January, the last month was taking the Green Goddesses back to the storage depot near Branston.
I think I can speak for most of my fellow squaddies when I say that we never once considered the money implications for ourselves, it was just a case of, there's a job, just get on and do it the best way we can.
