"We have given considerable thought to whether or not it was appropriate for the employers to transfer the applicant to the core shop even though it would have meant compulsorily transferring other employees out of the core shop against their will. We have noted that the core shop was recognised to be one of the less strenuous jobs in the foundry and we have heard evidence from the applicant's fellow worker that he himself had been transferred at one stage to the core shop for that reason. We therefore consider the provisions of Section 6(4) in trying to decide whether that was a reasonable step for the employers to take. It may have prevented the effect in question but we have not considered it an option which was practical for the employer to take due to the extent to which it would disrupt his employment relations with the other employees in the core shop. In reaching our own decision on what if any steps were reasonable and what is objectively justified and material and substantial we have considered whether there was anything more which has been suggested to us which the employers could do or which we felt was reasonable for them to do"
