Let’s remember that an adjunct lecturer or instructor is simply an off the street hire to teach a class that none of the full time faculty want to deal with. Normally those are huge, introductory level classes full of annoying freshmen. An adjunct is not on the tenure track and normally is only hired on a class by class contract.
Over my career, I hired a couple hundred adjuncts to cover classes for faculty who were on sabbatical or unable to teach for medical reasons. Some were very good. Others were awful and never got rehired. If you want to become a “professor,” an adjunct position is a good place to start. When we hired new full time faculty, good adjuncts had a leg up on the competition as long as they were female or minority. White men were moved to the back of the line by edict from the administration.
Normally, new full time people are hired as assistant professors and move up the ladder to associate professor (normally with tenure) and those who have a good record of published research can reach the top level of full professor. They are not normally awarded promotion. They must request it and prove they are worthy to a departmental committee, a college committee, and finally they must be approved by the top level of management. In my case, that was the university president. The “folder” they submit to the promotion and tenure (P&T) committee consists of proof of everything they have ever done. Most P&T folders are several hundred pages at a minimum and take hundreds of hours to prepare.
The guy in question here was simply a part-timer with no academic rank.
