Aunty B: What’s the right way to interrupt a colleague who just won’t shut up?

Dear Aunty B,

I read your column last week in which you offered some advice to a business owner who was having trouble running effective meetings. I’m also having difficulty keeping meetings in my business on track and I’m hoping you can help me.

My issue is I don’t know how to interrupt my staff when they start going off topic in the meetings. We have an agenda and for the most part, my team is good at sticking to the tasks at hand. But there are a number of individuals who like to use these meetings to talk, at length, about issues that are either not on the agenda or have been dealt with in the past.
