I've had a cold this week, not serious, but coughing, hacking, and sleeping a lot. And yet, I've taught all my classes. I wasn't nearly as good teaching as I usually am, but they were okay.
It got me wondering, though, how other peoples' schools handle short term instructor illnesses?
Here, you can just cancel classes.
Or you can email the department and ask someone to cover the class. (It seems to me that most of those emails are more for planned absences, such as for conferences, rather than for illness.)
I have cancelled classes in the past rather than try to find someone else to teach them, mostly because we teach an 11 credit load (with adjuncts teaching a 15 credit load as full time), so it seems harder to find someone with free time than it would if we taught 6 or 9 credit loads; easier than with 12 credit loads, though. But usually, especially with a cold, I just muddle through, do the best teaching I can, and that's that.
With a cold, I don't think I'm extending the cold. It's usually a week to two weeks, or, if you don't teach, 7-14 days, right?
But I feel bad about probably sharing germs with students and others.
I was amused, on Friday, though, when I taught with a really ragged voice (mostly trying not to talk), and after class, one of my students came up and did that thing where they apologize for missing class because they didn't feel well, and you could tell as the words were coming out of their mouth, they realized that not feeling well hadn't kept me in bed. On the other hand, if we all stayed home when we got a cold, we'd share them less, but my students would also have missed two weeks of classes this semester from my absences.
