Victoria Police has been charged with several bullying-related offences in an unprecedented step by WorkSafe.

The charges come amid allegations the force did not provide a safe work environment at a station in Melbourne's south-east.

A senior detective from the Monash Crime Investigation Unit has also been personally charged with two bullying offences over his alleged failure to "take reasonable care for the health and safety of persons who might have been affected by your acts or omissions in the workplace".

The senior sergeant, who has been transferred to a different station, has not been named by The Age for legal reasons.
