Most Civil Servants have to sign the Official Secets Act , which means you do not talk or write about anything you see in the course of your work to anybody.
Having said that the computerisation of records has made it a lot easier to obtain information which you should not be able to access.
I was a Civil Servant for 20+years, starting with paper records only, I left over 5 years ago and the amount of information I had access to when I ceased was unbelievable and there were hardly any checks on reasons for access.
I also have concerns about staff giving out information that should be kept private, I know of someone whos' mother was going in a home where the Social Workers knew the mothers income, when asked where the info had come from she was told Pensions section of waht was the DHSS.
I myself have received letters from power companies offering free lightbulbs if I am on certain benefits as I am on a qualifying benefit I sent for them and received them, I was either trusted to be telling the truth or the power company obtained details they were not entitled to .
You obviously are concerned about something are you able to give more details?
