I work in tech in an urban area where my close co-workers are outspokenly and vehemently liberal, and our lunch conversations generally include some sort of trump bash during some portion of the conversation. Our team is spread across the world and members can go years without ever actually meeting each other face to face.
Circumstances are such that we are all meeting for some workshops and corporate events, and several very well respected senior members of the team are on-site. Circumstances are also such that I met these senior members first before my co-workers did (I am a VERY junior member).
I have observed that these senior members, who are very well liked and extremely nice, are conservative. Furthermore, I have observed them taking several steps to hide it. I am not surprised, this area is nearly 100% liberal. They don't want to stick out.
How can I slip the word to my other co-workers to avoid the daily bashing of conservatives during lunch? We will be meeting later this week all together, also for lunch. The liberal and conservative parties haven't met each other in person. Only I have met both sides.
I understand it is not my personal responsibility to deal with this. I want to communicate that the topic is a no-go to my liberal senior team members, without seeming disrespectful, without raising an actual HR issue and without risking it happening. They are smart enough to know not to bring it up, if they were aware, but they aren't.
I want to indicate the situation to the other team members in a totally plausibly deniable way that cannot possibly make this MY issue. What can I do?
