SA hospital workers to walk off the job

Support workers at Adelaide's Lyell McEwin Hospital will walk off the job in a protest over proposed health reforms across South Australia's hospital network.

The United Voice union says it has concerns about what the changes, including the closure of one public hospital, will have on job security.

It says negotiations over the proposed transforming health reforms have stalled, forcing its members to take industrial action.

United Voice branch secretary David Di Troia says the government has offered no commitment on job security.

Thursday's action will include a stopwork meeting at the hospital before workers march on the office of local Labor MP Lee Odenwalder.
