Fellow educators - I instigated a formal grievance against my HOD however she asked for more time to respond and I left the school before it was resolved. My HOD then left the school and took up a new post as a HOD at an independent school. Would she have had to declare that someone had filed a formal grievance against her? What if she did not mention it at interview? Was she supposed to? Only asking as she shafted me and I'd like to return the favour.
