I stand to be corrected, but I simply do not believe that 5/4 is on the agenda at the moment. There has been some talk of 'buying' different packages of employment whereby you can do the 'worst' roster for the most money and then take some sort of salary sacrifice for a better deal. 5/4/5/4 would be a slight gain on 5/3/5/4 and would therefore attract a lower salary. You would then, for example, work your way down to 50%, no weekends or whatever and lose money accordingly. I have no idea how advanced those discussions are, if at all, but it is certainly something I would be looking at if I were a manager trying to entice my workforce towards lower pay. In principle it is actually a potential win-win for everyone and I would not dismiss it out of hand. I shall wait to see what appears...........
