Nassauman, Could you confirm the 5 lates-3off-5 earlies. So you could finish at 2330 local at the end of the fifth day and then three days later start at 0545 local. In my company that would be 2 rest days and one single day off.
The next day, if finished after 2000 local is a rest day and if starting before 0800 local the preceding day is a rest day. So if we were rostered that pattern, we would have rest day after late finish, three clear days off and then rest day before early start.
