Parcel Force/Royal Mail C+E driving: Good/Bad/Ugly?

Hi,my brother worked out of Wishaw via agency and said it was the easiest job he ever had
Also said all the RM drivers do is ■■■■■ and whine about everything and wouldn’t last 5 minutes driving for most companies.
As someone else has said they don’t take on drivers direct and you need to work your way up from being a postie
