Being invited to a disciplinary hearing by your employer can be a daunting and stressful experience.
Your employer is obliged to inform you of the allegations and evidence against you, and they should have a written and accessible disciplinary procedure to ensure you’re clear on what the process is.
The process in which your employer is expected to follow when taking any disciplinary action can be found in the ACAS Code of Practice, which includes the right of representation. Whilst this Code isn’t legally binding there can be consequences for your employer if they don’t follow this.
