I used to chair an annual event for 'women' - hosted by an international bank. The idea was to champion, celebrate etc.
Every time I went to the ladies', I was followed and that's where the real conversations happened - women would share that they're pregnant, but haven't told anyone at work. Or they were visibly pregnant and shared that they were concerned they wouldn't have their current job when they got back etc.
The (understandable) reluctance of many women to share issues they're struggling with out in the open/ with management at these events that are supposedly for their 'benefit'- is one of the reasons I created S.H.E.Strategy.
So they have a framework to figure out what their priorities/ needs are, and how to communicate with influence - to bring about change they need.
