Very easy to achieve that.
Completely separate off the letters and the parcels sides of the business from one another, then reduce letter deliveries to 3 days a week...
-Our parcel service becomes far more up to date, user friendly and convenient for the customer and recipient
-Our letter service becomes far more streamlined and cost effective compared to the current 6 day USO which is insanely inefficient.
-Redundancies available for the thousands of posties who are desperate to get out.
-RM becomes more profitable for investors
Everyone's a winner!
