I worked in retail for 38 years not always top pay but used my money wisely . After the company folded in 2009 between us our income today is the same as then and don't have to work for it .Allowing for inflation guess its less .Not sure how you work out £10 per hour equates to 30k per year .You would have to spend a lot of money in your firm to get discounts to bring it upto £30k and overtime is not quarateed especially when times are hard in retail
