The study found 73 per cent believe their company is committed to diversity and most employees agreed their organisational culture appreciates differences.
But employees were less likely to agree diversity awareness is a priority in their organisations and women rated their companies' DE&I efforts lower than men in every part of the survey.
About 67 per cent more women reported feeling that their organisation has a threatening work environment compared with men.
"This indicates that there is a larger number of women who feel that their work environment does not allow them to feel safe in expressing themselves," the report said.
Women provided significantly more feedback on DE&I. One female employee said: "Hard to narrow to one thing, but hiring and promoting diverse employees and managers will be important to including those voices in all conversations."
Men provided 573 per cent more "unsure" responses compared to women when asked how to improve DE&I.
An example of an unsure response from a male employee was: "I currently don't have any ideas here."
More than twice as many women recommended diversity training and education, and both genders equally suggested giving employees voice, celebrating diversity, inclusive collaboration, administering surveys, and enacting policy changes.
Not all supported more diversity and not all suggestions were directed in favour of increased diversity.
"Hire people who fit the job, based on qualifications not some other attribute. On the opposite side, if we are going to start to worry about these types of things instead of how qualified someone is, then I have some things I need to think about as far is this the place for me," one said.
The report authors said DE&I initiatives were most successful when supported by employees and should be implemented as a holistic system rather than piecemeal.
In a survey earlier this year of more than 400 human resources managers, more than half rated DE&I as a top priority for their organisations.
