Can you help with the challenge of keeping staff meetings fresh and interesting?

We are a 24/7 facility, so getting all of the employees together at one time to disseminate information is difficult, hence the monthly staff meeting. There are always current issues to deal with, as well as staff recognition and ongoing service projects, and I often try to add in training on being an effective communicator or discussions of how to control burnout/stress. But it’s become quite challenging to keep these meetings fresh and interesting.

Have you been to meetings that you have found particularily effective or interesting? Any team building excercises that you found helpful? Any resources that you can recommend?
