Changing one's job description after hiring is not fair, though.
I feel that you can change the job description and raise the standards,
but cannot fire someone if they cannot meet the new higher standards.
They would be given an opportunity to meet the standard, but not fired for
failing to be able to do so.
Firefighters are first to arrive at the medical call because they are close by
to respond within the first couple of minutes of a fire- the critical time between
a tiny fire and the whole building engulfed in flames. The ambulance with
the paramedics is running around all day between sick people and the
hospital, so they were not right in the neighborhood.
Once the ambulance arrives, the firefighters stay in the neighborhood, but
the ambulance leaves the area to take the patient to the hospital, so when
another one gets sick or hurt, the firefighters arrive first again.
Or the joke: Firefighters are first on the scene of an emergency because they
had nothing else to do. (So it's not an LOL joke)
