Im not sure how you would do it! But just a little bit of advise! When I worked as a despatcher we done a L-L-E-E-O-O rotation and it worked well!
You get an extra day as you dont start till late and you finish early so you really have three days off! You were a bit tired with the L to E! But was far better than a E to L!
You had more of a social life!! And didn't feel that you were constintly at work! So staff morale was good!
