Don't forget Adelaide
After the PER roster issue, MH could not get extended hour rosters back quick enough. His only mantra was 'call it whatever you want, just don't call it a 12 hour'. From then on the '12 hour' was banned in exec-speak . From a production point of view the 8 hour is the least inefficient for the company because the have to find you 40 hours of work a week, not 38. That 'extra' 2 hours is an RDO....in whatever form it comes.
What most here are forgetting is that the '12' hour became an 11.4 hour, as exec-speak mandated it. Not long after PER in ADL we went through our roster review. It is a lot better than 4on/4off although it incorporats a 8 hour day every 9 weeks. Question why the company would accept that over enforcing an eight hour. 8 hour shifts are very unproductive from a companies point of view. Do not be told anything else!
