Yes, such as the secret service, law enforcement, social workers.
Yes, there are 3 years of my life's work known only to me and my immediate superiors. It will stay that way until I shuffle off this mortal coil. I'm quite proud of that.
There are plenty of jobs around the world where confidentiality is of the utmost importance. One of the best examples is found within governments.
There is bound to be plenty of confidential information shared between high ranking members of governments, and this information is unlikely to ever be revealed to the general public.
There are, of course, loads of other examples of highly confidential jobs, including the following:
- Military officers - it's of great importance to retain certain information within the military, often relating to when and where units will be deployed. This is required in order to maintain the element of surprise over the enemy.
- Special forces - likewise, members of the special forces will receive information that will never be released to the general public. They also don't reveal their identities to the public even after they've retired.
- Intelligence units - MI5, for example, only allows its employees to tell a very select number of people about their job. Employees will be provided with fake career information for when other people ask what they do.
- Doctors - patient confidentiality is a requirement for doctors in many countries around the world. This is put in place so patients can come to doctors with their issues, knowing that their information will not be shared with other people.
As you can see, there are many jobs around the world that are very confidential. Ranging from hidden information to cover up roles, the general public knows very little about what's truly going on behind the scenes.
