Schools must provide Occasional Teachers with a key to the rooms needed in the assignment. This is for the safety of the Occasional Teacher as well as the students. There is an increased awareness from educators and the public in regards to the security of our schools and this is a crucial step.
It is inappropriate for the school to ask for a “deposit” of some item in exchange for the classroom keys. If you are asked to leave your personal belongings in exchange for the school keys, politely explain that you are aware that the keys are your responsibility and that you will be sure to return them upon signing out.
If any problems continue, get through the day, and give me a ring later on. We can discreetly and confidentially discuss it.
