The Night Shift and the Faulty Guard
Ridgeway Foods operates a packaging plant. Tomasz has worked the 10pm–6am shift for three years. The plant's conveyor has a guard that was removed six months ago to speed up cleaning; management knew and took no action. Tomasz also suffers from a diagnosed sleep disorder that his GP had told him to report to occupational health; he never did. One night, after his fourth consecutive 12-hour shift (a pattern management had imposed to cover staff shortages), Tomasz reaches into the unguarded conveyor to clear a jam and loses two fingers. Ridgeway's safety officer had recorded the missing guard in a log that was never escalated. Ridgeway argues Tomasz was the author of his own misfortune.
1. Assess Ridgeway's liability to Tomasz as his employer. What is the content of the employer's duty, and was it breached?
Read the worked answer
An employer owes a personal, non-delegable duty to take reasonable care for the safety of employees. The duty has several strands: safe premises, safe plant and equipment, a safe system of work, competent fellow workers, and reasonable supervision. It is a duty of care, not strict liability, but the standard is applied with regard to the risk and the practicability of precautions.
Ridgeway breached the duty on multiple strands. First, safe plant: the conveyor guard was removed and management knew, yet took no action. That is a plain failure to maintain safe equipment. Second, safe system of work: the imposed pattern of four consecutive 12-hour shifts during a staff shortage created fatigue risk, and the safety officer's log entry about the missing guard was never escalated, showing a defective reporting system. Third, supervision: no one stopped the practice of clearing jams by hand at an unguarded conveyor.
Ridgeway's argument that Tomasz caused his own injury does not defeat the claim, though it may reduce damages. An employer cannot discharge its duty merely by pointing to an employee's carelessness where the employer created or tolerated the unsafe condition. The employer's duty is to protect against the very risk that materialised.
2. How should contributory negligence and the sleep disorder be weighed?
Read the worked answer
Contributory negligence requires that the claimant failed to take reasonable care for his own safety and that this failure contributed to the injury. Tomasz reached into an unguarded conveyor to clear a jam. A reasonable employee might have stopped the line or reported the jam rather than reaching in. That is a plausible basis for a reduction.
However, the reduction must reflect the relative blameworthiness and causal potency. Ridgeway created the hazard, knew about it, and imposed fatigue-inducing shifts. Where an employer's breach is the dominant cause and the employee's conduct is an ordinary response to a badly designed system, courts reduce only modestly. The fact that the practice of clearing jams by hand was routine and unsupervised weighs against a large reduction.
The sleep disorder is more complicated. Tomasz failed to report a condition his GP told him to disclose. That non-disclosure may support a finding that he failed to take reasonable care for his own safety, especially if the disorder made him more prone to error on night shifts. But Ridgeway must show it would have acted differently had it known; if the plant was already unsafe and understaffed, the disclosure might have changed nothing. The disorder is best treated as a factor supporting a modest reduction rather than a complete defence.
Overall, a substantial finding of employer breach with a modest to moderate reduction for contributory negligence is the realistic outcome.
3. Could Ridgeway rely on the defence of volenti non fit injuria? Explain why or why not.
Read the worked answer
Volenti requires that the claimant freely and knowingly consented to the risk of injury, with full appreciation of its nature and extent. It is a complete defence and is applied narrowly, particularly in employment relationships where there is inherent pressure to accept working conditions.
Ridgeway would have to show Tomasz knew of the specific risk and voluntarily accepted it. Knowing that a guard is missing is not the same as consenting to the risk of losing fingers. Continued work in unsafe conditions, even with knowledge, is generally not treated as consent because of the economic pressure of employment and because the employee may reasonably expect the employer to remedy the defect.
Statutory provisions in many jurisdictions also restrict volenti in the workplace, and an employer cannot usually rely on an employee's acceptance of risk created by the employer's own breach. The defence is therefore very unlikely to succeed. At most, Tomasz's knowledge supports contributory negligence, which reduces damages rather than eliminating liability.
