In stories, especially creepypasta, its sounds more like a magical contract than a piece of paper
Like if a private organisation hired you to kill people, a NDA doesn’t somehow make that legal and you can’t get sued for breaking the contract.
So, what is the legal extent of NDA?
As with everything law related. It depends.
They are inforced arbitrarily and from ones I have seen suppliers use they are meant to protect trade secrets like sub part numbers or things being developed.
Can you give more specifics please? Which sub part numbers and things being developed?
Nice try, our direct competitor
I work for a company that uses NDAs, though I am not under one. Some of the things covered are our designs, our suppliers, and the names of our customers.
