If we're going to have a debate on it let's at least dispense with the hyperbole and discuss it sensibly. We're not talking about forcing members to reduce their contracts, we're talking about building a future resourcing mix that increases the part-time ratio over a period of time and addresses the dangers of ever increasing delivery spans to align aspirations with the long term physical sustainability of the job.Fish has raised a point which is worthy of discussion does the union cut it's losses and agree that the delivery span will drive the number of full time jobs in the future. I think most members would choose to remain full time even if it meant a longer span rather then opt to say a 3.5 span but be forced to reduce their contracted hours from full time to part time but let's have a debate on it.
The fatigue study as expected was a whitewash of skewed data and irrelevant conclusions, It was simply an agenda-led cherry picking exercise and an embarrassment to the union. No professional Industrial Engineer would have touched such an amateurish effort with a barge pole which leads me to believe that the union was as uninterested in getting to the truth about fatigue as the business was. The obvious union agenda was holding on to this notion of a predominantly full time resource mix at all costs no matter the possible long term physical dangers to staff.
Part of this study was supposed to look at business wide sick absence rates and reasons, IHR rates and reasons and reduced opportunities for redeployment but none of that data has surfaced, It really was a sham exercise and not even worthy of discussion.
If you really want to debate the impact of longer delivery spans I would suggest doing one for at least a month first then come back and we'll kick it off from there.
