At my firm, there’s a tradition for managers to do a short speech at our office Christmas party. It’s been a great year in politics and I want to really celebrate it. I think most decisions went the right way and I’m sure most people agree. Should I just go ahead?

Hold on a minute, before you start pouring the eggnog, just remember that the world of politics can be incredibly divisive - especially if you've all had a drink or two. You may be convinced that everyone in the office supports your political views, but you could work alongside "Remain" or "Hillary" supporters who have not openly promoted it.
