"Sleeping underground is not only dangerous, it is illegal under Section 9(3) of the General Duties and Conduct Regulations. It is an offence to sleep underground. This year there have been a number of accidents where the victim was probably asleep, one was fatal.
"I am writing to you about employees found sleeping underground in the mine. Sleeping underground is dangerous. There have been a number of incidents including one fatal ....
"In the past men found sleeping underground have not always been dismissed. In some cases for example fines have been imposed.
"The mitigating circumstances as I understand them are: (a) Mr Williams' domestic circumstances; (b) the environmental conditions at Mr Williams' place of work and (c) the amount of overtime worked by Mr Williams.
"I feel that Mr Williams has control of these circumstances and if he felt unable to sustain a home life because of excessive overtime, then he should have let his immediate superiors know that he was not available for overtime of the degree which was expected of him"
"13 The respondents contend that dismissal was fair on the ground that it was for conduct which was illegal, contrary to the Regulations and which constituted gross misconduct under the Code. They say that as overtime was voluntary individuals were expected to know their own levels of endurance, and that in any event the hours worked by Mr Williams were no greater than those he had worked in the past. They say neither the domestic situation nor the overtime constituted `substantial mitigating circumstance' within the meaning of clause 34 of the Code. They defined substantial mitigating circumstances as circumstances outside the employee's control such as unconsciousness induced by heart attack, a blow on the head or drug abuse, and said that if employees felt drowsy they were expected to keep awake by activity or to speak to their superior and go above ground.
"18 It was also submitted that the respondents' interpretation of `substantial mitigating circumstances' as being circumstances outside the employee's control such as sleep induced by heart attack, concussion or drug abuse, was unreasonable in that drug abuse was more controllable than sleep induced by exhaustion."
