They almost all have a second job.

>A 2015 survey found that 62 percent of adjuncts earned less than $20,000 a year.

In general, no. See https://en.m.wikipedia.org/wiki/Adjunct_professor

Sadly, in the US, even the “tenure track” full-time professors are seldom full-time lectures. Their most valued contributions are:

- obtaining research grants

- department administration

- image management

They also sometimes teach courses, but more often than not, that duty can be given to a combination of adjunct professors and “graduate teaching assistants,” ie doctoral students.

Much of it I’m okay with organizationally except for the money/workload balance. It’s a race to the bottom to overwork and underpay for teaching duties.

It used to be, but has been trending away from that for a while.
