Hello, my name is Ben and it is my pleasure to be able to assist with your question today.
T is impossible to predict at this stage how this will end up. It is for the employer to decide how serious this breach was, if it has breached any specific policies, if any damages have occurred, including to reputation, the potential for a serious incident, etc. These are all factors that will be taken into consideration by them and they will eventually decide which route they want to take. Before any disciplinary is held you will need to be told the exact allegations against you and also the potential outcome, so that is where you will find out what could potentially happen. Even then, if at the disciplinary you manage to successfully defend yourself the penalty can be reduced to just a warning or even nothing.
