If an employee requests to record a disciplinary/grievance meeting - can you refuse this?

An employer is entitled to refuse an employee permission to record an investigation or disciplinary hearing. At the outset of each hearing, the Chair of the hearing or meeting should request that all attendees to turn off their phones and to make clear that recording of the hearing is not permitted but that detailed notes of the hearing will be circulated afterwards to all attendees. A note that this has been explained to the employee at the start of the hearing should be made and it should be noted that the employee confirms that they are not making any recording of the hearing.

If an employee records the meeting covertly, that may amount to a breach of the implied term of mutual trust and
