The only problems with that reasoning is that women have been in the workplace for hundreds of years (domestic service, textiles, etc), and human resources started appearing in about 1900, approximately 50 years before mixed workplaces were common.
If you were right, literary works like Nikolai Gogol's "The overcoat" wouldn't exist. https://en.wikipedia.org/wiki/The_Overcoat
HR was invented because workplaces didn't work well, and that was about 50 years before mixed workplaces were common. You're just projecting your biases and ignoring the facts.
