Hi, thank you for your message. I am sorry to hear about your situation.
1) I would advise that you raise a grievance with your employer through their grievance procedure. You can also follow the ACAS code of Practice on Disciplinary and Grievance Procedures here: https://www.acas.org.uk/index.aspx?articleid=2174. The emphasis of this Code is to try to resolve grievances informally, without reverting to a formal procedure, or to resolve them with the help of a third party (mediator). If an informal grievance is not possible you can start a formal grievance. This should be done in writing and should set out the nature of the grievance.
2)Your employer should invite you to a meeting following the grievance. I would recommend that you bring a companion to the meeting.
For more information on who you can bring to the hearing please visit: https://www.citizensadvice.org.uk/work/problems-at-work/disciplinary-meetings/who-can-accompany-you-to-a-disciplinary-meeting/
3)Contact ACAS. The ACAS Helpline can give advice on internal processes and policies to help you through this (0300(###) ###-####.
4) As a last resort you will need to take the employer to the employment tribunals. You will need to contact ACAS if you wish to take this course of action.
