I always preferred 12hr shifts. The reasons are numerous, but I
think that the main one would be the time spent on days off
means that you get away for long enough to relax properly.
I have worked with 8hr shifts before, they always seem to drag
on and suddenly those 8 hours have started to stretch towards
10. The other big disadvantage with the 8hr shifts is that when
there is need to provide cover for sickness, or holidays etc there
is usually some poor sod who ends up cover their own shift and
then having to come back 8hrs later for another.
Just my 2 cents worth
