No it wouldn't.The 1-3 hour later start times at DO's would give them the time needed at MC's to get data into the system from the barcodes and then generate the walks.
The entire network would be pushed back 1-3 hours not just delivery.
It's actually the fact that the mail would arrive at the mailcentres later that would force the later starts in delivery.
There's no savings in dynamic walk generation unless you can send people home at zero notice, that would mean employing everyone on zero hours contracts but if you have that capability you don't need dynamic walk generation because you can just stop paying people the minute they walk back into the office anyway.
That's what they're after with flexi-time, annualised hours and a commitment to deliver, a version of zero hours contracts.
