The dreaded GM, where to start.
To keep it simple this is the one where you can get fired, the outcomes are as follows :
I could speak on this forever, to keep it short you will need to find a GOOD fed rep, they will support you
through the process. You will be served with form 163 which will explain the allegations against yourself, assuming you haven't committed a criminal offence this will be the most stressful part other than the hearing itself. My advice is to immediately seek support with your mental health, you can do this via OH referral from your line manager.
