Without giving away the whole story here’s the thing: There was a near accident in my classroom and I shouted at a student, the student cried, the student made accusations that were never proven. I was dismissed. At the time I had an ongoing grievance against my HOD and I was suffering from depression. My union is supporting my ACAS claim for unfair dismissal. My question is this: I want to work; I need to work; but my supply agency requires a reference from the SLT. Should I give the agency my HM’s contact details?
