Unfortunately, I can't provide you with a lot more detail. It was very specific—whether you encountered a hostile work environment, whether you felt not included—but I don't have specifics about what they mean by “hostile work environment”.
Certainly in any sort of company where fewer than a quarter of the women who are working inside a lab or inside a STEM occupation are in an environment where they are not necessarily brought in or feel part of the organization, or they are not supported or treated appropriately, I can see how, at the very least, they would feel not included, but to understand the hostile working environment, we would need to dig into it further.
