Feedback training for managers and professionals

There's a world of difference between constructive feedback and personal criticism.  Although we all give it sometimes, personal criticism says more about the person giving it than the person receiving it.  Our highly acclaimed London UK management course, "Skills with People", gives training in constructive feedback.

It puts people's backs up when in the name of feedback they hear opinion, judgement, generalisation, unsought advice, or questions implying criticism.  This training will teach you to be much more specific, factual, generous spirited and constructive with your feedback. 

But how can you be sure this feedback training is for you?
