Allegations of bullying have emerged at a council in Melbourne's outer south-west.

Two councillors at the City of Wyndham have reportedly written to Local Government Minister Melissa Horne over claims of bullying involving a councillor towards council staff.

Councillors Josh Gilligan and Mia Shaw say Wyndham's chief executive officer commissioned a report into the matter, but it has not been made public.

“This report, protected by privilege and deemed confidential, is alleged to contain damning findings of a councillor towards several council staff that is understood to be so serious that the councillor would face dismissal were an employee relationship present in the organisation,” the councillors wrote.

“Now, we ask you to obtain a copy of the report, review it and make a determination on the bullying allegation involving a councillor's interaction towards staff.

“Staff must have confidence that they will be protected from reprisal for bravely speaking out, and, most importantly, it must not be left to councillors to deliberate on the method or outcome in dealing with serious workplace health and safety matters that a colleague is responsible for creating.”

Wyndham City says the matters are confidential, and Local Government Minister Melissa Horne says she is seeking advice on the issues.
