"Adjunct", that means she doesn't really work for the school.
An adjunct professor is one who holds a temporary appointment. So, yes, she is probably not on the full time staff and probably is not in a tenure track.
Since an adjunct professor is more akin to an at will employee and since it is summer time, perhaps the President and Provost of Bentley will decide before late August that she is too whacky to be an adjunct professor at Bentley.
