Pros
Driving all day is no problem, listening to music, working alone suited me fine, not having to deal with as many people as you would in store.
Cons
Oh where to begin. Pickers not having orders ready on time. Constant calls about why you are late (never my fault - traffic, wrong orders, etc.) Management very arrogant and hypocritical and lack basic understanding of proper scheduling delivers. Rota's and hours changed at last minute notice all the time. Not getting a break (illegal). General awful management - to be fair Asda as a customer were always OK with me, but to work for they were very unprofessional and unorganised. I've heard my particular store in Cumbernauld had very bad management through the years, and has only recently came under new management, time will tell if there is improvements.
