Thank you. Potentially this can result in dismissal. This is because if you have been continuously employed at your place of work for less than 2 years then your employment rights will unfortunately be somewhat limited. Most importantly, you will not be protected against unfair dismissal. This means that your employer can dismiss you for more or less any reason, and without following a fair procedure, as long as their decision is not based on discriminatory grounds (i.e. because of gender, race, religion, age, a disability, sexual orientation, etc.) or because you were trying to assert any of your statutory rights (e.g. requesting maternity/paternity leave, etc.).
So even if you had done nothing wrong, or you had done what you did because this is what you were shown, the employer can still dismiss. So this may be unavoidable if the employer believes you were in the wrong and justifies dismissal. As such the best thing to do is admit any wrongdoing, i.e. try not to get out of it if you have done things wrong, but explain why you did it and what prompted you to do it, such as training etc. Show remorse and ask for a second chance and further training on this to ensure you avoid doing the wrong thing again. It may be the best way to try and salvage this situation.
