Although this thread seems to have erred from the original dicussion of what is a good shift, it's a good one nonetheless. With regard to who get's what it all depends on the rest of the package.
Spannersatcx gets no shift pay but they get a goodish basic. Hispeedtape gets a bucket load of shift pay but from my experience with his employer basic is total poo. Penndoff and me get not much shift pay, a tad below average basic pay but it only costs me £700 for a fortnight in BGI for a family of 5 all in. Other places get loads of approval pay, some get 1000's, some like where I used to work get £10 per month per A/C but only if one flew into your station that month, if you didn't get a Classic that month, sorry no tenner. It's all swings and whatsits. Of course we should all earn more but who outside a/c engineering gives a toss??
Anyway 4days on 4 off, 4 nights on 4 off is the best.
