I have taken a seasonal temporary position in a national high-street shop.

The hourly rate paid at the store in which I am based is 10% less than the nearest store 14 miles away. The unofficial reason for this is that, surrounding the other store are a number of specialist shops which pay their staff more and it is reasoned that the company has to pay the staff based in this store more to attract them.

I was wondering is there a legal definition of regional weighting and is it classed as a Genuine Occupational Reason in defense of an Equal Pay claim?
