I previously left out that aspect of confidentiality, and it often led to me hearing my reports mirror my confidentiality pledge right back at me
It felt wrong, but I didn't know how to describe why until I realized how an abuser abuses confidentiality to maintain their abusiveness.
Sunshine can be so valuable when it comes to abusers. A few years ago, I didn't realize that a colleague was being abusive until I shared with another colleague what he had said privately about wanting to have a private conversation rather than openly discussing a topic in a shared channel.
It doesn't matter whether it's written or said on camera or discussed in person. If someone (especially holding power or seniority) doesn't give a clearly meaningful reason why something should stay private, raise a red flag high.
