Environment? Well... I'm biased, since I dearly love HH.
And fortuanately for me, I work in a rural setting.. country roads, lovely scenery, meadows, cows, rail fences, hills and valleys, babbling brooks.

Yep.. you get the visual.
So it's very liberating and refreshing not to be confined to a unit floor.. and instead of hearing intercoms, pages, loudspeakers, etc., we can listen to our choice of music while drinking coffee in the morning as we toodle down the road in our vehicles.
It would depend on the geographical area, I suppose. Personally, I'm not a city person, so I wouldn't care too much for HH in a city setting.
I can say that regardless of the setting, HH patients are always more than pleased to see us arrive at their front door. Thye welcome the visits warmly and I have yet to meet a patient who does not. It is also a unique setting in that you are in THEIR home, on THEIR turf, and it is something we respect at all times.
Not sure if this is what you meant by "environment", but for what it's worth.
As for workplace "issues"... I suppose these are common in ANY nursing environment, but since I am one who arrives at the office before the rest, and thus gets OUT before the rest arrive, (most of the time), I'm not really exposed to these "issues". If I hear things that don't concern me, I just go on my merry way and ignore it.
I feel that our agency is pretty good at teamwork and being helpful not only amongst the roadwarriors, but between the office staff and the road nurses as well. I'm sure every agency is different, some may have more issues than others. I can only speak of what I know and have experienced with MINE.
We do have bi-monthly nurses meetings during which issues are aired, changes made, insevices held.
