If that's the way you want to approach it, which does have some value, the starting question is "why isn't the legal system sufficient or able to address this?" Which is a many-layered question but let's go.

The needs of a small organization are different from an entire state. Transgressions can be disruptive or destructive to organization-scale relationships without rising to criminality.

And the the traditional feminist answer of "why can't the legal system address sexual assault" is "it wasn't meant to." A famous quote on this is that from a woman's perspective rape isn't illegal it's regulated. The definitions of it and the standards to be met for deciding it has taken place were decided by men, to enforce against other men. The way women feel about their interactions with men has not traditionally been a prioritized factor in the legal system.
