Change management involves modifying the known environment, regulations, and rules for operational staff (e.g., Air Traffic Services personnel from Operations or Engineering). Such changes often face uncertainty, risk, and potential resistance. To address this, effective change management is essential. As an ANSP, we understand the specific needs of stakeholders and how successful changes can be implemented. Key aspects include considering the change itself, involving employees, trade unions, works councils, and prioritizing clear communication to all parties involved.
