According to the Daily Mail,
Sports Direct bosses asked warehouse staff to press 'happy' or 'sad' emoji buttons to say how they felt about their working conditions - before using fingerprint recognition to ID unhappy workers, according to a trade union.
Is this really being done?
Can it be done? I imagine that it would require a camera behind the emjois, to capture images of fingers which press them. Even so, how would they link those to employees?
