I think there are considerable barriers and challenges, not just to working women, but I would say students in our universities. These people are fairly privileged and have access to a lot of resources. The women at École Polytechnique were targeted because they had access to resources and education.
The important piece is to look at this as a comprehensive issue within which we want to nest tailored responses to marginalized groups, but it must be addressed comprehensively to make sure that the access to resources is available to anybody who needs it whenever they need it.
I think a big part of this is comprehensive policy development, so I would encourage you to consult the UN Women virtual resource centre to end violence against women and girls, or endvawnow.org.
