Around 40% of voters support Donald Trump in some way. Are you sure you really want to discuss politics at work? Do you want someone wearing a MAGA hat explaining to everyone why immigration is too high?
Because that is what real political discussion will involve. In fact, I suspect many people who are advocating for politics at work, actually only want people whom they agree with to be able discuss policies that they generally agree with.
So for me, as long as the company does not prevent political activity outside of work, I am happy to have work be a neutral zone where people from opposite ends of the political spectrum can just work together on how to make money for the business.
