There are asshole professors all over. Just ask catsix; I’m one of them. 
But I don’t know that my attendance policy really all that rare. Of course when people start complaining about it, you only hear stories about the about crazy professors who have bizarre expectations, not the 98% who are reasonable. (That 98%, of course, are probably adhering to school policy, which, in every institution I’ve ever attended or taught at, states that students with documentation from a medical professional stating that they are not well enough to attend class must be excused and allowed to make up the work.)
While it’s true that I am a deeply sympathetic and compassionate human being and a true saint among professors, really, the energy I’d expend fighting about a draconian attendance policy is just simply not worth it. I would think that if a professor established policies based on the notion that no students are ever going to miss class, they’d get a reality check pretty soon. In my 90-student lecture, I’m almost gauranteed to have at least one student get seriously ill and end up in the hospital every semester, not to mention the dozens who come down with sniffles, flu, mono, strep, and all that fun stuff. And broken legs, and court appearances about illegal music downloads, and terminally ill parents, and best friends dead in car accidents (2) and sudden diagnoses of pschiatric disorders, and . . . (All those examples are Real Life Events from the last two semesters.)
Who the hell wants to have a knock-down drag out fight over every class a student misses?
Though if so many other professors really are such dicks about it, that would explain why the drippy-nosed disease vectors come groveling to my door—though they could have just STAYED HOME AND READ THE SYLLABUS where my wildly liberal attendance policy is clearly spelled out.
Now, the people who wander in the last week of the semseter and say, “Like, I missed some class and stuff because I, like, came down with ebola last month? Could I, like, make up that work? And, um, that’s why I did bad on Exam 2. Can I retake it?” Sorry, Charlie. I don’t actually expect you to READ the syllabus, but it is nice to be able to wave it under your nose and point to the part about timely notification.
