The problem, as I've experienced with this, is that it requires cooperation of the other part; more specifically, it requires them to acknowledge these feelings as being pertinent to reality. Take this example from the article: "When you said, 'I’m not happy with your work,' to me in front of the team, I felt embarrassed because it didn’t meet my need for trust and recognition. Please, could we set up a weekly one-on-one session to share feedback in private?" What when the other party says 'well I didn't mean to make you feel embarrassed, and if you did, that's your problem - just change the way you feel about these things because this is just the way things go around here.' What then? And a similar response can be phrased for every statement that uses this terminology/method.
