he is the boss... and at some point the ceo must have said it was ok...to me it doesn't seem that strange that management would pull work from all sources and make the presentation. in theory all the work produced by everyone should be on the same "page" and represent the same points the company is trying to sell.

not to sound stupid but I would imagine the boss could go thru the project and figure out which talking points are the essential ones..knowing the type of business you do and the type of business they are trying to represent ion this presentation. when I worked for the government this was a fairly common way of presenting information. upper management or a specific person presented info, not usually the creator of the study.

if the presentation goes well, and it should if your document is correct and they are pulling info from it, then there should be no need for drama..your work was used to help the company out. either way you helped to benefit the outcome.
