If employers know of a health and safety risk — or should have known, based on the current state of knowledge at the time of the incident — they will be liable if an employee is injured, killed or suffers illness as a result of the risk and they failed to take reasonable care. This general duty of care is particularly important where there is no specific statutory regulation, such as when dealing with repetitive strain injury (see Chapter 7) or stress, bullying and violence (see Chapter 8).
