This a fascinating an important topic, and I congratulate you for embracing this approach. Your experience brings to mind some important attributes and caveats with psychological safety.

• It is best accomplished on a micro, or team, level. The more people who are involved, the more complicated it can get, because everyone has different life experiences, with different degrees of emotional fragility or resilience.
• The more groups in an organization that actively practice this, the more this mindset will permeate the organization.
• People at the highest levels of the org chart can undo all the positive accomplishments of managers who implement psychological safety in their teams.
• It’s a slippery slope from constructive psychological safety to silos, which are just groups of people who provide some modicum of psychological safety to each other in the midst of a toxic culture.
• At one time, Google was hailed as being on the forefront of implementing psychological safety. Not so much anymore. Economic challenges and associated stresses cause people to revert to a “me first” mindset, and the psychological safety bubble goes “pop”!

Sincere best wishes to you and your team!
