This is highly variable between practice environments, but shouldn't be.
OldJob: 10-minute door-to-doc time! YOU are responsible for seeing all of these patients SAFELY and within the standard of care. Charting?! You can do that on your own time; and it will not be paid. Should the 10-minute door-to-doc time EVER be breached, then frantic phone calls will go out to every credentialed provider in the area to come in and help. If they cannot come in and help; then they will be subject to scrutiny, and will be threatened with multiple nonspecific actions. Furthermore, at the beginning, in the middle, and at the end of every shift... we will discuss every metric with you... and it will be painfully obvious that this is all beyond your control. Nevermind that; we'll make you feel bad about it anyways... and your paycheck will suffer. If you do agree to help; you used to be given a small bonus; but not anymore - you will come in and accept that all of your metric-based bonuses (which are already ruined by our poor staffing decisions - as all the metrics are already F*cked) will already be denied.
NewJob: We would like it for every patient to be seen in 30 minutes; but we understand that given the resources, this is not possible. Hell; its not even realistic for every patient to be seen in less than the time that it takes to deliver a pizza... and we're not talking about screwing up a pepperoni-and-mushroom pie, here. You will not be penalized because we are boarding eleveteen patients in the ER and your triage nurse cannot adequately direct a patient who demands a "smoke break" and twelve phone calls before she decides to HAVE an emergency (but not before checking in!) to come back to the primary patient-care space.
I had no idea how bad OldJob was.
