So, I am uncertain of how to handle things on Tuesday.... I need some advice, please. Because the wrong recommendation was already sent to higher ups, it will defeat and mess up all of my own efforts, and this is an assignment from the CEO himself. And I was not copied on any additional email sent with my finalized and revised copy, so I am assuming my final version was never sent to the higher ups.

In order to prevent a HUGE mistake from happening that makes ME look really bad in front of the CEO, should I follow up with my boss on Tuesday when we return to work again to ask if my final version will be sent so as to make sure the work is done correctly?
