South Australia’s unions want Return to Work changes extended to all industries, not just police.

The state’s Return to Work Act comes into effect on July 1, 2016, at which time payments to injured workers will be provided for only two years unless the injury is deemed “catastrophic”.

The act defines “catastrophic” as an impairment of 30 per cent of the whole person, or ongoing psychological injury.

The SA Police Association has been campaigning to raise public support for the bill it says will restore “worker protection and safety conditions” for officers.

But SA Unions state secretary Joe Szakacs says he wants to make sure it applies to all workers.

“I welcome these direct conversations around our emergency workers, which I think the community very much supports,” he told ABC reporters.

“[But] we would argue — and we've put this directly to the Government — that if there is going to be a passage of improvements of any entitlements for injured workers through Parliament, then ... that entitlement increase should be rolled out to every worker here in South Australia.”

Mr Szakacs has contacted the State Government over the matter.

“Should there be improvements to workplace benefits for those categories of employees [emergency services], then we would be putting to Government, asking them very strongly, that those improvements be rolled out to the entire South Australian workforce.”

Public Service Association and Ambulance Employees Association want their workers to be exempt from the two-year cut off period.

They are calling for a broader exemption to be included that would apply to all frontline emergency service workers.
