How much do professors get paid?
For those of you wondering what adjunct teachers get paid, here is my paycheck.

That is a one-month paycheck for one 3-unit class. Each district that I teach at pays me only once per month, not every two weeks. I receive five paychecks of equal size for this particular class. So, the total I get paid is $2,508.90 gross, $2,372.20 net, for one semester long 3-unit college class. Excluding summer classes, that means at this particular district if I were to pick up my maximum load of 10 units, both in fall and spring, then my yearly pay would be $16,726 gross. So that’s the short answer. As an adjunct, at an average district I get paid $16,726 per year.
By state law those 10 units are 69% of a full-time workload, and are the maximum that I can teach at any one district. So, just for laughs, let’s say the pay stayed the same and I got an additional 31% workload at another district, then I would be pulling in a total of $21,911.06 gross per year after we include that extra $5,185.06. This is all assuming a perfect workload, however, and it is never as easy as all that. For starters, at this district my department only offers 3 unit classes, and thus the most I could ever teach is 9 units per term, since there are no 1 unit classes. Also, I’ve never been asked to teach a full 9 unit workload, they just don’t have that many classes available. Sometimes I get two classes, but as you can see from my above paycheck, right now I am only teaching one class at this district. I currently am on the books at three districts, buy was only given classes at two of them.
Your pay will vary from district to district, especially when you teach at a district that has quarter terms instead of semesters, but for the most part the above numbers are the relative average.
Again, for the above district I am only allowed to teach a total of 10 units per term. Any more would make me a full-timer and qualify me for absurd luxuries such as medical and dental benefits, as well as paid time off. So, in order to carve out a living, I work at several different districts, picking up classes wherever I can. This is not an easy thing to do. Most districts are never hiring, not even adjuncts, and those that are seldom can give you more than a single class. Even if you do get a couple classes at a couple districts, they often overlap, and you are forced to decline some classes based on the unfortunate physical limitations that prevent you from being at two places at once. Damn you, Physics! I have found that once I tell a chair, “Sorry, but I am unavailable for that class,” then I almost never hear from them again.
So what do adjunct professors really get paid? Well, as you can imagine after reading the above, it varies from month to month, and term to term. The ideal would be to get four classes, which something I seldom manage to accomplish. Right now, I am teaching three. One is at the semester-based district, which means 5 equal paychecks from January 31-May 31. The other two are at a quarter-based district, which means three payments, ending on March 31. About six weeks ago, I found out they had another class for me in Spring (April-June), but as you can see, this will cause my monthly income to drop when the semester-based class ends in May. Aside from summer (which I will discuss in just one moment), the next semester is in the fall, and that means even if I manage to book classes (of which there is no guarantee) then I won’t get paid again until September 30. Hellllloooooo unemployment.
What about summer, you ask?
Here’s the deal with summer terms at most colleges: they are short, offer only a fraction of classes, and usually only go to full-timers and those with seniority. A summer class, on average, is about 6 weeks long. You get paid the exact same amount for this class as you would a spring or fall course, because technically it is the same amount of working hours compressed into a short, yet more intense, span of time. So take those five months of paychecks I was getting in the spring, and then compress them into one big fat lump sum. Considering that you get in six weeks what would have taken you five months to receive, summer classes are seen by most teachers as a gold mine.
The drawbacks are that these classes are long, often 4-5 hours per day, 4-5 days per week. As such, you might only get (or be able to handle) one class, and I have never heard of a district that gives anyone more than two summer classes to teach.
I just found out today that I will be teaching one class this summer. So instead of June, my paychecks will stop coming on July 31. I have no idea if I will be getting any classes, at any district, for the fall. If I do, the earliest paycheck is September 30. So, as I said before, Hellllloooooo unemployment.
Uh, hello?
