Delays to improving New Zealand's workplace health and safety regime seem to demonstrate either a complete lack of understanding of the causes of the country's poor track record in this area or a cynical worldview in which workers are valued less than other production inputs and the law's delay is just another tool to avoid overdue change.
Concerns have been expressed regarding the difficulties and cost of changing the current legislation (under which New Zealand has one of the developed world's highest rates of workplace death and injury), of the role employees will have in any new regime and of the need for certain industries to be exempt, on the grounds they are somehow different from other occupations.
All of these concerns miss the point - whether wilfully or otherwise.
Citing the cost of change as a reason to continue the present set-up suggests a mindset where employees are valued solely in terms of the commercial gain their efforts accrue to any enterprise.
Rather than attempting a cost-benefit analysis of safe work practices, it might be better to conclude that if safety is unaffordable, the enterprise is unsustainable.
