The joint statement has not yet been agreed. There was a couple of issues still to be resolved and the Royal Mail manager leading on it went on leave.
The union can not have an issue with either the IWT or geo route, they are sound tools , in fact geo route is used world wide.
However there are elements of the IWT which needs to be update for example once you have done your redirections then where do you take them ? plus how many times do you clear down your ips or secondary.
In terms of geo route there is still live testing going on. The joint statement would have said that both systems are fit to use and if the live testing shows a need to update the system then a new version will come out currently we are on iwt 6.25 and geo route 2008. All revisons should then have a review if already introduced to see if the new version changes your office.
Both of these systems have to have joint input if it is to be accurate.
Now in terms of 100 BSi being agreed , well there is an issue here , Royal Mail changed the criteria for what they compare productivity on , they now use weighted items per work hour to compare offices and decide who are in the upper decile and delivery offices are put into 4 groups one is cities , one is towns, one is rural and the other surbubria.
Now in terms of the IWT and 100 bsi , acas guidelines state that 75 BSI is the measure which should be expected by a trained worker, over 75 bsi should mean that some one is fully trained , has a full head of work and is motivated. Royal mails claims that the pay rise , supplement and attendances and shorter working week provides motivation.
Now in terms of speeds for walking they have been reduced and there are different speeds for different terain, equally there is a different speed for paths , standing at the door , attendance calls etc which means that no one has to walk at 4 miles per hour for their whole delivery round as all of these elements mean that the speed is reduced. The union with Royal Mail are currently testing some elements on geo route live, however geo route 2008 providing all the sid and sarah is done and checked , the aplus is up to date and the loops , traffic is correct should provide for a reasonable revision but all of those factors have to be done.
By the way remember if your at 75 bsi on the IWT then you do not have to get to 100 in the first revision you can agree the target under the aims and objectives and therefore you can agree to set the IWT at 85 or 90 reducing it from 100.
No there is no agreement to use the IWT for absorbtion.
Your divisionaL rep is correct providing you are happy that you have measured your office correctly, you have inputed all the correct info into both geo route and the iWT then it would be safe to proceed. However make sure your satisfied with the model week and your involvement.
