Psychological safety is a key ingredient for high performing, effective and happy teams.
When people feel unsafe, they tend to engage in less helpful, more basic behaviours, such as being negative, blaming others, needing to be right, catastrophizing by blowing things out of portion, over-reacting or even withdrawing, resigning and giving up.
On the contrary, when people feel safe, they are more likely to be open, calm, curious, willing to collaborate and find win-win solutions.
