Many mainstream businesses expressed their support for the original bill. Those good employers should not have to compete with businesses prepared to cut corners and risk workers' lives.
So what are workers, their unions, and good employers particularly concerned about?
Health and safety representatives for one thing. Health and safety representatives are elected by workers. Our current law, flawed as it is, requires them in all workplaces when workers ask for them. But under National's new law, workplaces with fewer than 20 employees won't be required to have health and safety representatives unless they're in a "high risk" industry. Unfortunately the Minister of Labour won't tell us which industries those are.
This means that up to 300,000 working New Zealanders won't have access to one of the most effective ways they can keep themselves and their mates safe at work.
Health and safety representatives will have the power to stop dangerous work, issue improvement notices, accompany WorkSafe investigators and get answers from employers when issues are raised.
These are important powers. But they'll be denied to workers in small sites.
The cruel irony is that in any given industry, small workplaces are less safe than larger ones, due to a lack of knowledge, time and resources. This change threatens the workers who are already the most vulnerable.
We also want personal protective equipment, not an allowance to buy our own. At the CTU, we've represented a lot of workers who were hurt or killed after their employer gave them an allowance - often insufficient to afford the safety gear it was for - instead of supplying it.
Yet after lobbying from bad employers, the Government is endorsing giving workers an allowance instead of the gear they need to be safe on the job. This means more risk - especially new workers who may not be able to afford the right gear up front.
These are just two of the areas where our Government has listened to reckless business interests instead of putting the health and safety of working Kiwis first.
