O K , I am going to stick my neck out here and add some very subjective stuff , based on what has been touted around word of mouth in the U K dubland for decades...
It was always said that "Marks and Spencers like to employ Jehovah's Witnesses because they believe them to honest, conscientious workers"
That was decades before any employment law was framed to deal with "Equality in the Workplace" or "Equal Opportunities". This Awake comment refers to a situation that, if it ever existed, was so long ago that this H R Consultant must have retired years ago!
As I understand, it was said that Pioneers often could get temp work at Christmas .....but I never heard of real career recruitment at M & S. I never knew any dubs who worked there..
BTW.. I never put the theory to the test and applied in the name of a J W !
