Warning to all of you in non-managerial position: be very wary of confidentiality proclamations. It happened to me that my manager ran immediately to the CEO, when I said I'm going to start looking for a new job in 3-6 months time. I told him that I specifically don't want this information to leak, but yeah, everybody knew it by the next working day.
Lesson learned: never tell anything sensitive or important in your 1-on-1s with the manager. Except pleasantries, hobbies and other useless stuff.
