OCC,
Have to agree with you!
I currently work 12.5hrs shifts on a 4/4 basis, and am concerned that moves may be taken in the near future to change to the 8hr, work every bloody day of the week, pattern!!!!!!!
12hrs are effective! Continuity is much greater, and therefore better decisiions taken as the big picture is known, and not just the last 2hrs you came on shift. If you get my drift?
