Career path of "instructor" (message from a colleague)

As a matter of fact, there are at least two types of “instructors” in this
campus:
(i) TEACHERS who spend most of their working hours in duties related to
teaching. However, they are not regarded as “teacher.” The university fails to
provide a reasonable justification for the difference in name and in reality.
(ii) TEACHERS who spend most of their working hours in teaching, and try to do
some research. They are mostly young scholars, who know the very truth that
research is important for their academic career. Unfortunately, their rank is
called “instructor,” which does not sound like a research position.
Consequently, they are neither regarded as “teacher” nor “researcher.”
Both kinds of instructors mentioned above deserve the name of “teacher.” The
university should also state clearly their career path, such as the criteria
for an instructor (TERM B) to be promoted to an assistant professor (TERM A) or
above.
