I am currently a school librarian in a private school. My principal gave me two subjects (grammar & creative writing for high school) to teach that is not in line with my work. I sent a letter to inform her that I decline to continue teaching the subjects so I could focus more on the task at hand which is being the librarian. She responded that under RA 4670, a teacher status applies to a school librarian and I am required to teach not more than 6 hours a day. I have an overload pay for those two subjects but I find it too low for the responsibilities that go with the teaching assignment.
Now she would like me to justify why I should not accept the loads given to me. Could somebody enlighten me on this matter. Thanks
