I work at a company which recently hired a female developer for the first time.
We currently have two bathrooms available: One with two male standing toilet and a regular toilet (with a door), and another with just one regular toilet.
Up to now, since we were all men, we used both bathrooms. Now, we have put a sign at each bathroom door to indicate gender.
But it seems to be fine for us employees to use it while our female coworker is not in the office.
I've talked about this to the manager as I find this anti-hygienic. He said it is anti-hygienic but due to our current situation (almost 15 males everyday at work) it is the best thing they can do. That it is everybody's responsibility to leave the bathrooms clean.
Also, I think the manager hinted me that as long as she doesn't know, there should be no problem. The expression for this was:
Ojos que no ven, corazón que no siente.
Google Translate: Out of sight out of mind.
I could translate it but I don't know if it will lose the meaning.
That exactly is what keeps bothering me. How is this handled around the world?
