Currently "planned" four and a half hour delivery spans that in reality take over five hours plus the outdoor meal relief to complete, when done something close to "properly" (eg. standing still while "filtering" mail for next address from the bundle, then walk to next address).
Some duty holders on blatantly too big walks for the amount of IPS/parcel sorting/portering they are expected to do, have not been taking any paid meal relief since our Delivery Methods revision years ago, but they have not been finishing 40mins early or accounting for these untaken paid breaks with overtime claims. making some of these crazy duties look achievable. Yet some of these same OPGs come in for overtime on their day off regularly, having given away almost half a shift's pay by never taking breaks on their scheduled five days!
The future's bleak- the future's black... To twist a well known advertising slogan.
