Employment – 'Worker'. The employment tribunal had held that the claimant was a 'worker' for the purpose of s 43K(1) Employment Rights Act 1996, so as to entitle him to bring a claim of having suffered detriment under s 47B of that Act on the ground that he had made a protected disclosure. The Employment Appeal Tribunal, in dismissing the respondent's appeal, held that the tribunal had made no error of law, but had reached conclusions that had been properly open to it on the evidence.
