This is a weird debate. We have pulled away from any revisons talks or activity and forced Royal Mail into agreeing to abide by the terms of the agreement and various other issues and yet we get criticism for standing our ground and not allowing Royal Mail to bully us or break the national agreement. It really is a funny old world.
Fish I can understand the question and statement will this just be another agreement that Royal Mail will break. However we have something which they need and that is agreement on revisons and if they break this one then they will not get another revison. This has forced Royal Mail to agree to honour the national agreement. What other alternative was their do nothing and allow Royal Mail to do what they want ? Well we were not prepared to do that.
Now let's look at the BSI issue in context cause it not as simple as saying that an office is at 100 and another office is at 75. It's the measurement which is based on averages and not Indivduals unlike some other industries.
The out put of geo route is first set at an optimum of 100Bsi then manuel adjustments are taken into account which includes attendance calls , time locks , traffic , welfare breaks etc. No office at the end of that is at 100 BSI.
The indoor element is different and depends on the size of office , the mix of firms , the start times , the type of mail , amount of packets , whether you have secondary sorting , amount of redirections and again the system is based on averages. This is why there is a range of performances across the UK no two offices are alike.
No I don't believe Royal Mail will put in hours to bring someone down from say 100 on the indoor as their next step is to move to the upper decile.
