ABC employees have fired a warning shot at their superiors, telling them that staff have lost confidence in their ability to manage the organisation.

More than 60 Radio National staff met at the broadcaster's Ultimo office on Thursday.

They unanimously passed a motion of no confidence, citing "systemic failure" in senior radio management and "the erosion of the editorial and managerial responsibilities of executive producers".

In a copy of the motion obtained by Fairfax Media, staff called on Community and Public Sector Union organiser Sinddy Ealy to "immediately convey" their concerns to ABC managing director Michelle Guthrie and ABC staff elected director Matthew Peacock.
