Organizations with speak-up cultures are safer, more innovative, more engaged, and better-performing than their peers because people feel sharing their truth is safe and worthwhile. Not having such a culture can sometimes have life and death results. Two psychological phenomena affect decisions to speak up -- gaslighting and toxic positivity. Gaslighting occurs when someone is manipulated by psychological means into questioning their own reality. Toxic positivity is when we’re allowed to talk only about good things and the future -- no lamenting the past or talking about real challenges at hand. When a broader spectrum of emotions is safe and welcome within organizations, we can make better, more sound, holistic, and wise decisions. This article shares strategies for creating such a workplace.
