As Teacher Librarians, we uphold the principles of librarianship outlined by the ALA for our students to have the freedom to access information and to serve them in becoming information literate.
On campuses where libraries may have been closed for years, many have either never known or forgotten the role of libraries and teacher librarians. Our positions are unique to any other on campus and it is our job to educate our campuses about our role and to model the value of librarianship through our programs, collections, and collaborations.
The other pages go into the contractual evidence for when you are asked to take on duties outside of your job description. This page is aimed to provide you with more practical advice on how to do this.
The best defense is a strong offense. Keep your schedule filled with library orientations, book talks and standards-based lessons. Document your duties and projects when you are not teaching.
Make it clear that making you a part-time librarian will deprive a large group of students of important library content and services. Show your past and future schedule as evidence of all the classes that will miss out.
Remind your administrator that your position is centrally funded to provide the school with a full-time librarian, to serve all class periods of the day. (But don't forget that you are also entitled to a conference period.)
Reach out to your chapter chair and possibly your area chair and area rep for support.
A long-term solution is to win better contract language to prevent this in the future.
