Hi,

Obviously this is an idiom and cannot be taken literally but the picture of someone doing this or at least attempting to do it usually suggests that they are very angry, have lost control and are acting in a furious way.

The new management decision is different from the new management's decision, isn't it? In this case, ie. the first, it's the decision that is new, not the management; furthermore it's a decision concerning the management. I'd just like to make sure I understand it right!
