Encouraging administration...

I am in the process of trying to encourage the administration in our school to employ me on the basis as a teacher/librarian for a couple of days a week in the school library. Previously they have had an Educational Support Officer working full-time who was not library trained but was the only person willing to take on the job when the previous TL moved on. This lady has now retired and saw herself as merely the 'caretaker' of the library as she had no real passion for library work. They have now got someone who is training to be a library tech working three days a week and she is passionate about libraries. I am hoping that between the two of us we can re-invigorate the school library (and perhaps build our own empire?), and make it more of a place of learning than a place with some computers. Fingers crossed there is an extra bit of money in the budget that will enable the school to pay me as a TL.
