Luis Velasquez and Kristin Gleitsman:

Leaders who model optimism set a positive tone in the workplace, empowering team members to recover from setbacks. If you want your team to navigate challenges independently, the worst thing you can do in the face of a setback is look for who to blame. Developing the organizational muscle to pull together to overcome setbacks is crucial. And while blame is not helpful, team retrospectives can help the team collectively get better at anticipating and avoiding similar setbacks in the future, creating a sense of shared accountability.
