Wizo,
I appreciate your support for the system but as has been said you cannot substitute GDOs for Leave - they are 2 seperate beasts. Those of us with kids need to keep GDO ( max 5 ) for the kids sports day, Xmas pageant, watch your kids in competitions on that weekend your working etc etc etc.
I happy to go to 5/4/5/2 but not with the restrictions being imposed.
