For example, at work my supervisor or co-worker and I communicate by writing and at the end, he/she keeps the note (on which we wrote down) as an evidence so is there a law that prohibits it? In a hearing world, there's a law that doesn't allow a supervisor or an employee to tape-record another employee's conversation at work.
My supervisor told me to prove that it's not allowed to keep a note that we wrote down after I asked her to throw it away. If there is a law regarding this, please help me find it so I can make a copy and show it to my supervisor.
