That's the rear cup holder, so the fix is simple. Twist the drink clockwise a little as you're picking it up, and the rubber insert should stay put. Unfortunately, that doesn't work with the one in front.
I remember my first vehicle only had one cup holder and that was squeezing whatever you were drinking between the bottom and top of the bench seat. It only worked well with bottles, but I guess that was better than the rubber spacer following you into the office.
