Pretty sure you have to use the restroom that you identify with, depending on your pronoun. Thats just the way it is.

Imo. If you have an office full of women in the building, do the courteous thing & use your gender specific bathroom.... unless it's an emergency.

Although, if you feel like being a dick ( no pun intended ).... maybe your identifying as a woman at that particular day... & naturally should use the ladies room.

I should mention that we had a problem with restrooms in our building. It has shops & offices. The bathrooms for the shop areas was part of the problem. The women's room was loaded end to end with motorcycles & parts. & the men's room was disgusting af. Some gross mf in the shops refused to flush the urinal or the toilet, all the time. There was no way I could have a customer, or female employee use the restrooms on the shops side. So we started using the restrooms on the office side...
