HiSpeed Tape, Do all you can to resist 7on 3off... I've worked it and it is a killer. By day 5 you have had enough, interest wains and so by consequence does flight safety. It takes all your days off to recover as well. I now work 2 earlies / 2 lates, 4 off, it is by far the best I have worked. Yes it can be tiring but not as bad as a 7day shift by a long way. As a side line seems to be developing, I get £1750 for this shift, any comparisons welcome !
