Really? I'm always careful to not entertain or ask people in to my hotel room (male or female; you never know these days), and I don't visit other colleagues in their rooms. My office door is usually open, and if it's closed, the whole world can see in through the glass front because I keep the blinds raised. I am careful to keep what I put into emails is always professional and unambiguous. And, I'm a potential target and work in a hypersensitive environment.
Oh, and re: the last comment, what I read in private, I don't keep on my desk. Why would I want to invite trouble?
Really. I work in a lab for a large corporation, so there are never Hotel rooms involved or anything, but what you describe about that environment is perfectly reasonable.
I've had to take the mandatory training for over 25 years now, so I've seen the rules change over the years. It used to be just keeping a good distance and never being alone with other people was sufficient, but this last go 'round my answers to the quiz were checked "wrong" because I'm overly cautious. I was informed that had to be changed because I would be creating a hostile work environment. I told them to pound sand because I worked it out so I only deal with computers and test equipment, there are never any other people around me anymore. It's mostly because they all got laid off, but it's made my life less fearful.
You mention an office with windows...first, that's a luxury only executives get. Secondly, it affords you no protection when words are what can get you in trouble. You would have to tape everything to get partial protection.
I wish I could just telecommute the way I used to. Life was great, but then we got a boss who loved to "manage by walking around." He was an asshat, ruined everything.
