Police in leadership roles are behind the majority of bullying behaviour found to be endemic throughout the NSW police force.
Despite being rampant, bullying, sexual harassment and discrimination within the police force are going largely unreported, a wide-ranging review revealed on Thursday.
Failures of leadership and culture were blamed for allowing these "unacceptable behaviours" to flourish.
The review of thousands of current and former employees found 30 per cent had directly experienced bullying in the past five years, leaving many of them feeling "scared, belittled or humiliated".
Direct managers and supervisors were found to be responsible for the bulk - or 44 per cent - of the alleged bullying.
One anonymous respondent said bullying was as much a part of NSW Police as wearing a uniform.
