Y’all have to answer to boards of various kinds with completely unreasonable expectations. (I have good friends who work in a library. We live in completely different worlds, you and I.)
This seems to be a wisdom issue both for the worker (e.g., avoiding burnout or even just resentment) and the management (workers who have external principles can be more valuable but they can also be more difficult to manage even decently, i.e., with average ROI)
Your comment reminded me of Bunny the accountant's statement that Skeeve must charge the going rate to have the kingdom on a rational budget and Skeeve deciding to refund taxes to those who complained the most (in one of Robert Asprin's Myth Inc. books). What could possibly go wrong? :-)
