While the Plaintiff was employed by the Defendant as a labourer, he lifted a bundle of timber onto his shoulder and suffered severe pain in his lower back. He was taken, in pain, to hospital where he remained for two weeks. He was diagnosed as having a slipped disc and eventually he had an operation which improved matters. He reached a condition in which he was compelled to discontinue working for the Defendant. He was unable to sit in a soft chair, kick a football or ride a bicycle. He could not bend to lift his young child.
