Many thanks for your patience. Now that you have been dismissed you only have a couple of options available to you - one is to appeal their decision using the internal appeals procedure and failing that, to make an unfair dismissal claim in the employment tribunal.
The appeal is made with a view to overturn their decision to dismiss you and to try and get your job back. There is no guarantee it will be successful and nothing will force them to take you back on. It is something that is entirely in their hands. Ideally you want to be remorseful about what happened and to be given a second chance, whilst being fully clear about what has caused this. On the other hand if they know the full extent of what caused the issues they may be reluctant to allow you to return for fear of this remaining an ongoing issue which cannot be resolved and causing further conflict between staff. However if you do not tell them the chances are that you will be in the same position in the very near future.
If the appeal is unsuccessful then your only other option is to consider the unfair dismissal claim. The issue is that in the circumstances I am not too certain you will have a good case. You were clearly guilty of misconduct and whilst this may have been caused by another employee you did not give the employer the full opportunity to try and resolve this because you were not fully open with what you were going through. Whatever the reasons for this they did not have the opportunity to try and fix things and in the meantime you were guilty of misconduct on more than one occasion.
So whilst you may not necessarily be able to get your job back, I would hope that you would at least be able to negotiate something with them which will not adversely affect your prospects pf getting work in the future, such as a positive, or at least a neutral, reference.
