My best professional relationships are between people who are confident enough to take direct feedback and appreciate it rather than resent it.

However, my worst professional relationships are with people who will rebuke your feedback whether you Crocker it or not. If you're direct, they'll say you should have been more diplomatic about it, but if you're diplomatic, they'll say you're being dishonest and should have been direct. There is no right way to approach it, these people will always find a way to criticize the delivery, and to delegitimize the feedback because of it.
