Generally transparency and truthfulness work. When people are honest and straightforward in respectful ways, it saves time and helps people get to the root of a problem. On the other hand when tales are told and falsehoods spread, issues gain unnecessary complexity, worry, and fraught.
It's best to seek out transparency and truthfulness as often as possible and exemplify that in your own work. Superficiality and inauthenticity is easy to spot and creates distrustful relationships and cultures. So simply put, be transparent and honest with respect, empathy, and care. Onward.
