The NUJ and the International Federation of Journalists have called on journalists to assert their right to refuse dangerous assignments such as covering the war in Iraq.
The call follows the case of former ABC journalist Richard Gizbert (pictured), who lost his job after refusing assignments in Iraq.
Aidan White, general secretary of the IFJ said: "The issue here could not be more clear. A media worker's right to refuse a dangerous assignment and an employer failing to take responsibility."
The NUJ and IFJ are asking their members to contribute to Gizbert's legal fund. Despite winning his case, Gizbert has yet to receive any of the £99,000 award because ABC is appealing.
