Providing library instruction, often via one-shots in someone else's classroom, may reduce feelings of agency or job control for academic instruction librarians. This study addresses potential differences in job control across core responsibilities, specifically looking at the difference between job duties overall and instruction responsibilities. As we consider the characteristics of library instruction, we should examine how those characteristics impact librarian agency in teaching spaces and acts. For job control regarding instruction, training and experience may have specific impacts and should be pursued as a way to empower academic library instructors.
