At my company (it's firm with about 900 people) we have an internal feedback tool which we can login and write someone a feedback. The feedback is completely open-text with no limit on number of character.
Using the feedback system is highly encouraged in our organization and many people use the system. and it's not anonymous so you get to see who wrote you the feedback.
One important characteristic of this system is that your manager is able to see all the feedback you have received. (it's only you and your manager)
In my opinion having your manager sees your feedback results the feedback to be less candid, as people who writes you feedback would automatically be more careful.
It also leads to situation where people will go and write something negative about you with the hope that it gives you some mental pressure to change since your manager is now aware of it - which I don't think it's constructive way of brining about the change.
I would like to know your thoughts on this? Should the manager be able to see feedbacks out of the box? Or should it be kept private to you and only share it with manager if you wish?
