Unfortunately, without the additional information requested in my first/previous response, I will not be able to give you detailed advice to your question, but I will be able to give you a general answer, which I hope will be of assistance. If you are able to supply the additional information later, please do so and I will then come back to you with a more detailed answer.
As explained, if an employee makes a formal complaint to their employer of bullying, harassment or any other issue, the employer has an obligation to carry out a formal investigation of that complaint no matter who it is made about. Once the employer has done that, they would either dismiss the matter as unfounded or, they could hold a formal hearing to speak to the person the complaint was about.
After that hearing, the matter can be dismissed in no evidence, or if found against the person, disciplinary action can be taken. That could be a warning, written warning, final written warning , dismissal etc.
If a hearing does take place and is found against you, you would then be able to appeal that with the employer. If you then feel the whole presses was carried unfairly etc, or leads to dismissal, then you could challenge at an employment tribunal.
I hope this helps clarity the matter.
Please come back if I can assist further.
