One example of an experience I made, of the positive sort:

I asked my wife to look into our job postings and point out what bothered her. We fixed some formulation details. This has been a year ago. We receive much more applicantions of female software developers now.

One of the negative sort:

A leaving employee made it her last act to introduce unisex toilets at the office. We thought why not and changed labels. Today a lot of new visitors are confused. They insecurely point to the door: can I go to toilet here?
