Many NSW police officers are too afraid to report rampant bullying, sexual harassment and discrimination over fears it could destroy their careers.
High levels of these "unacceptable behaviours" have continued across the force due to failures of culture and leadership, a wide-ranging review revealed on Thursday.
The review of thousands of current and former employees found 30 per cent had directly experienced bullying in the past five years, leaving them feeling "scared, belittled or humiliated".
One anonymous respondent said bullying was as much a part of NSW Police as wearing a uniform.
Additionally, almost one in 10 respondents said they had experienced sexual harassment in the past five years - with one per cent reporting having been sexually assaulted during the same period.
