"The general first instinct is to look at something and say, well is it discrimination or bullying or harassment or whatever, and then make an action plan rather than dealing with the root of the issue," she said.
"The answer is to understand the perceptions of people and their conscious and unconscious biases - and that's the starting point."
Changing the view towards inclusiveness and diversity in the workplace was multi-faceted according to Workman-Stark, who said it involved looking at everything from an organisations demographic makeup, to its policy and practice.
Part of her role in Canada had also involved changing how the police department viewed itself.
"In policing there is very much a focus on proving masculinity - proving you're strong and powerful and don't show emotion or weakness," Workman-Stark said.
"But there is a cost to that, either with officers not coming forward to show they have post traumatic stress disorder or other challenges, and also where people who don't fit this mould become isolated. So it's looking at how organisations work to overcome that."
Sharing stories around this had helped, but she said organisations needed to be open about the rationale for change and highlight the benefits of having a diverse workforce.
