Can you explain how your company uses ROWE? Was it there when you started, or did you witness the shift from hour-based work/pay to results-based work/pay?
I work in the same place as Jonathan, and have found working in a results only work environment to be an extreme step up. I started after the transition, and it was a very obliviously different environment than anywhere else we work.
The way we work is that we have very focused week or month or quarterly results we are responsible for, and we have a very transparent way of seeing who needs to do what and what is getting done. Beyond that, it's a big part of our culture not to be negative is someone chooses to work different hours or out of the office. It's their results to complete, and they know how they work most effectively.
