i posted the other day about being signed off sick with stress and anxiety . i hae spoken to my union about an oh appointment i have this week and been told they may want access to my medical records from my gp . i feel really unnerved by this and was advised it would be in my interests to give permission . i am not comfortable with a stranger picking over details of my medical history at all as the gps i have had i have known for years . any advice ?
