Your group doesn’t function like you think it should.
At your next group meeting, give a book report on a subject that addresses your particular concern. It could be something like 5 Dysfunctions of a Team, Radical Leap, Drive, Jamming, Breakthrough Teams, etc.
Sure, you can try to ask your boss to give you some time on the agenda, but if that’s not likely, just wait until the end when they usually say, “Does anyone have anything they’d like to share?” That’s when you speak up and say, “Yes, I’d like to tell you all about this amazing book I just read.”
Of course, you’ll have to be brief, but that’s better. You can even choose to only talk about a specific chapter each week, or if you like to read alot, maybe you talk about a different book each week.
Maybe things won’t change after your first week, or even your 6th week, but over time, I’m sure something will start to happen. People will talk. You’ll be known for something.
What type of reputation do you want to have? Go ahead. Create it.
What kind of team do you want to have? Do your part to make it happen.
