10 hour days? 60 hour weeks? Good gracious me, I never realised you chaps had it so easy these days. I never signed on for a pension in '77 because I was fed up of 12 on/2 off 12 hour day rotating shifts. To save you bothering with the arithmetic, thats a 72 hour week with one weekend in two off. On a VVIP Squadron. I don't know what the sharp end were doing.
Upon joining 'Big Airways' at Heathrow I found myself working 60 hour weeks, but actually getting paid for the extra 20 was something of a novelty.
