The board will recommend councils introduce a clear procedure on how individuals can raise issues of concern.
LGMB chief executive Judith Hunt said employers should offer protection for whistleblowers so they can raise issues in confidence; advice on whom to raise issues with, whether they concern a manager, a director or a chief executive; and a timetable for action by the employer so the individual can feel confident the issue is being dealt with.
Ms Hunt said: 'About 90% of councils have adopted the LGMB's code of conduct for local government employees. There is reference to whistleblowing in the existing code. But I think we need to make it clearer and stronger and we will be issuing detailed guidance later this year.'
