there is a simple solution, royal mail should return to the approach they agreed in 2006 they CAN afford to pay for chage. government money has been secured & colleague share can be repackaged in to basic pay & more money will be generated by the introduction of automation.
but their offer remains at 2.5 % which is a joke & this is conditional on postmen & women accepting all their previous strings

most of which WILL IMMEDIATELY REDUCE PAY

a strike is the only way royal mail is going to listen.
