That last part, “you are embarrassing me,” suggests an element of narcissism. It personalizes the feedback, something every leader should avoid doing.
Also, all caps suggests shouting, which suggests a lack of emotional control, something good leaders sometimes pretend to do strategically, but no good leader ever does this accidentally. (I give an example here: https://demodexio.substack.com/p/the-hearts-of-men-american-... )
Good feedback is specific and individual. What Gary said, in this example, is almost scientific in how precisely bad it is. He is emotional and non-specific. If a worker has made a good-faith effort and failed, this kind of ranting doesn’t help the worker, and if the worker is operating in bad-faith, then you’ve encouraged them to continue because you are shouting at the room rather than singling them out, a fact which convinces them you don’t know which workers are operating in bad-faith.
