I am a teacher (SLT) and have to provide two references. Obviously one will be the head, which is fine, but who do I put as the second? I have been at my place for over 20 years and many people who have line-managed me in the past have now gone and we are not in touch. In my current role, only the head and deputy are above me. Others are on the same level as me and don't really know what I do. The deputy also doesn't really know and is also one of the reasons I want to leave as he is pretty toxic so I don't want to put him.
What do I do?
