As a teacher I sometimes feel like there is a mismatch between the amount of work I do and how that work is counted towards meeting my job requirements.

Like most teachers I'm expected to teach a certain number of courses. But it doesn't matter if it's a course I've taught before, or a totally new course I've developing it's all counted the same.

Designing a new course is much harder and takes much more time than teaching the same thing I taught last year to new students.

It really discourages revision and improvement too. Every year I try to improve or update my course design, but this is never as much as I would like, and very limited if I'm teaching something new. But I have no incentive to do so other than wanting to teach better. The practice fits right in with the academic ethos of free labor called "service," though.
