There are always lots of things that don't seem to get done during organizational changes. Instead of wasting energy trying to assign blame or worrying about why those things aren't getting done, step up and do more yourself! Be ready and willing to take on a new assignment, stay late so that an important project gets done on time, or take on extra responsibility. It will be noticed, because companies seek employees who look for ways to do things better, more efficiently, or with fewer resources.
