Sounds like a great opportunity; I agree with the PP's experiences and the 6 items/suggestions already mentioned are about exactly what I'd suggest too.
People do "wander off," - to smoke, hit vending machines and who knows what else. I'd be curious how they plan to involve the greeter in that issue. It's something that could become contentious if they expect you to try to stop people or warn them against leaving, KWIM? I'm just trying to imagine what that would look like, because a lot of places are also reluctant to try to tell people how long the wait will be (especially if it's on the longer side) or "where they are in line" because then people want to leave and go somewhere else, and EMTALA worries enter the picture.
A couple of other things you'll want to know details about
- How they plan to ensure your safety. It would be ideal if you were kind of working in tandem with security, with the volunteer tending mostly to hospitality items and security attending to situations that can turn dicey quickly.
- Pay attention for any suggestions that are inappropriate for the role being designed. Every once in awhile, in seeking to make the most out of the opportunity for a new role, someone will make a suggestion that is simply outside the scope of that role - - such as, I could see someone saying, "Hey, and while they're out there they can be an extra set of eyes..." Well, no, a volunteer is not there to make sure people aren't shooting up in the WR bathrooms, for example.
- I would suggest they route all complaints or patient concerns about condition (which you absolutely will hear/receive if you're hanging out in the WR) directly to the triage nurse, or whatever their practice is right now without volunteers. All of that should be kept completely separate from the greeter role; trust me when I say that you don't want to be put in a position where you're
expected to call back into the department every time someone reports that their ankle pain has now just morphed into chest pain and they need to be taken back immediately. :- /
I don't think it'll be too boring, one way or another!
