If you absolutely demand change you need to have an answer to allay the manager’s fears that the changes you require will be a net negative for the group; that unserious gossipy annoying group that is setting the current bar for success.

From the inane gossipper’s perspective you could appear easily distracted, argumentative, and unserious. You’ve declared that their stress management rituals may be such a hindrance that you’d reject a promotion to avoid participating. That answer could gain you enemies even if you don’t even interview if it’s not kept confidential.

I hope this is received as contingency planning and not an insult. I don’t think those things and I also hate work gossip, but in this scenario you’re the out-group until you get in. It behooves you to become a quiet friend instead of gossip fodder. I hope you can play this field successfully and good luck!
