52 The defendant, by its agent, Mr Young, knew that the plaintiff was a worker who was prepared to work in the bush wearing worn out footwear that, to the plaintiff's knowledge, exposed him to the risk of injury. The fact that Mr Young asked Mr Geeves to check on the plaintiff's footwear leads me to conclude that on 13 May 1997, Mr Young was far from satisfied that the plaintiff had heeded his earlier admonition to replace his boots as they were dangerous. In the light of this knowledge, the defendant clearly had an obligation to ensure that the plaintiff was wearing appropriate footwear on and before the day he was injured. The only step taken by Mr Young to discharge this obligation was to ask Mr Geeves to call upon the plaintiff. Mr Young was unaware whether or not Mr Geeves had done as he had asked him and between 13 and 20 May was unaware of what the plaintiff was wearing on his feet. A prudent employer would have called on the plaintiff as he was working at Eagle Spur within a day or two of Mr Geeves' visit to ensure that the plaintiff was wearing boots that did not expose him to risk of harm. This the defendant did not do, but this failure will not visit it with liability unless a prudent employer would have not only visited the plaintiff, but also told him not to work in anything other than spiked boots, or alternatively, enquired about the traction given by the rubber soled boots and if told that they were slipping, then prohibited the continuation of work while wearing such boots.
