That's where you need buy-in from management. One of my past employers had a presentation series like that above, and if you were scheduled next, it _was_ considered work that you were responsible for, and counted towards more or less a half-day.
I haven't been at my current employer long, but from what I've heard about our frequent engineering meetings and their presentations, they do the same thing.
