Would you say that your organization has a safe working environment? Why is it important to ensure psychological safety in the workplace?
A safe working environment is critical to effective teamwork. It develops direct communication, honest feedback, and a willingness to go above and beyond through constant signals of belonging.
Learn about the key attributes of a safe working environment and why it’s good for workplace culture.
The Key Attributes of a Safe Working Environment
In a safe working environment, employees are willing and able to speak out, regardless of the hierarchy of the company. The group is concerned with one task: solving problems to promote success. This means that even the low-level intern has the ability to speak to the CEO, which makes them feel secure in their importance to the team. Though they may be a small cog in the machine, they are essential to its operation.
In a safe working environment, team members feel valued. No one wants to feel like they’re not appreciated. Safety lets team members feel like they belong in the group and have something substantial to contribute.
Note: safety does not imply niceness. Sometimes, courtesy must be put aside to allow for direct, unadulterated feedback. However, in a safe working environment, this bluntness comes from a place of care and a genuine desire to develop success.
Belonging Cues. A safe working environment provides a constant stream of belonging cues. These cues create a feeling of safety and comfort within the workplace and address three specific topics: connection, future, and security:
- Connection cues allow team members to feel as though they are supported by the group while being valued as individuals. Connection cues include physical connection, active listening, and small courtesies.
- Future cues let team members know that they have a future with the organization. Future cues include discussions about upward mobility, correlations between team members and model employees, and conversations about long-term goals.
- Security cues let team members know that they have permission to speak up without fear of losing their position. Security cues include the embrace of feedback, the promotion of team opinion, and the acknowledgment of strong work.
Examples of belonging cues include:
- Interactions in close proximity
- Eye contact
- Back-and-forth communication
- Energized conversations
- Open and honest dialogue
- Physical interaction (when appropriate): handshakes, fist bumps, and so on
The Benefits of Psychological Safety in the Workplace
Benefit #1: Chemistry. When team members repeatedly use belonging cues, they develop strong chemistry with one another. It sends a message to team members: you are a part of this team and you belong. This creates magnetic workplaces that nurture efficiency and cohesion. Team members communicate quickly, contribute new ideas regularly, and give their input energetically.
The Allen Curve
Thomas Allen, a professor from MIT, wanted to understand the science behind group chemistry. Through his research, he discovered that successful groups had one thing in common: their desks were in close proximity to one another.
As a result of this discovery, Allen developed a concept he called the “Allen Curve.” The Allen Curve displays the correlation between physical proximity to frequency of communication. Essentially, the closer team members are to one another, the stronger their chemistry and their resulting work.
Benefit #2: Willingness to Go Above and Beyond. When employees feel valued and supported in the workplace, they are willing to go above and beyond, even if the problem at hand is not technically their responsibility. Rather than spending a significant amount of time and energy strategizing, teams dive into issues head-first. They’re even more willing to work after hours to resolve the issues.
