During your first few days in prison you will be allocated a Personal Officer. This is a prison officer who has been assigned to act as your point of contact while within prison, and is the officer who is expected to provide a “reference” for you whenever you apply for jobs, change of status from Basic to Enhanced etc.
The duties of this officer are not very much, but a good officer will come and speak to you and ask if you have any issues they can help with, a poor officer will introduce themselves once and then may favour you with a grunt as you pass on the landing.
