Thanks for the replies.
All the time off is obviously the major plus side to this but it’s having to wait 6 weeks for your next full weekend to come around, that will take it’s toll I’m sure with a young family. It’s encouraging to hear the people who have done it saw more positives than negatives though.
I have first hand experience of a shift pattern change completely flipping a great job upside down, so it is a concern. Nothing is set in stone and it could be very well be another pattern, so will have to wait and see.
