Usually, I poll my students at the beginning of the semester and voluntarily tweak my office hours if someone can't come to any of them (or offer office hours by appointment when appropriate). So I don't, in general, have a problem with doing this.
This semester, however, I am teaching two sections (100+ students each) of a very large centrally coordinated course. There are several other instructors and many graduate student TAs. All students are welcome in any and all office hours.
With that many students and so many office hours to choose from, I feel less accommodating with respect to modifying my hours. A large part of this hesitation is that I have extra responsibilities associated to the development of this course, so I'm already spending more time than usual on it. AND I'm applying for jobs.
I chose my current office hours for time management purposes. I've been asked by a few students if I could move one to a different day (a day that I usually work from home) or take appointments outside of my regularly scheduled office hour, and I really don't want to. In fact, I feel a little bit like it's inappropriate for them to make the request in a class this large and with so many resources already available.
Is it unreasonable for me to flat out refuse to change them?
