Unless you have the opportunity or considering applying to get a job at Aldi Asda etc etc why bother your self on what the wage is or what the increase is or might be.
From what my Daughter ( Aldi 27 years)has said there`s not a big turn over of Aldi Drivers,when they recruit its usually down to .expansion.
Also it not third party hear say they DO load and unload their own trailer. Nearly all local deliveries due to regional depots opening.
