Not allowed to see CCTV before a disclipinary
I have an upcoming disciplinary concerning how I spoke to someone in store. The complaint used the word "aggressive" to describe how I acted. I've already said what I said was unprofessional but don't believe I was aggressive in the manner that is being made out.
I have asked to see the CCTV but have been told by my manager that it is not relevant, they have viewed the CCTV and it is not being used as evidence by them. They have also said that it has been deleted as the incident was over 30 days ago.
Can I complain about this and say it's unfair I can't use it to defend myself?
