Deputy chair of the Westmead Medical Staff Council Jenny King said doctors were concerned it took speaking to the media to achieve a result. "We don't want to be ignored," she said.

Westmead Hospital is faced with the prospect of having no interventional radiology services from next month unless it can come to an agreement with the specialists, who have collectively resigned.

The revolt among staff came after the dismissal of Westmead's head of gastroenterology department, Jacob George, last week, who raised concerns with management about the lengthy wait times.
