Oh well,
I will just chip in the one I work and believe me, it is comfortable;
NN O LL EE OOO
N-Night 2100-0700
O-Off
L-1300-2100
E-0700-1400
With the overlap on the last early you can acctually get off at 1300, that give you a full afternoon off, then 3 days Off, and you start at 2100 on the fourth day.
Not at all bad considering.
Cheers
