An open door policy (as related to the business and corporate world) is a communication policy in which a manager, CEO, president or supervisor leaves their office door "open" in order to encourage openness and transparency with the employees of that company. As the term implies, employees are encouraged to stop by whenever they feel the need to meet and ask questions, discuss suggestions, and address problems or concerns with management. An open door policy serves to foster an environment of collaboration, high performance, and mutual respect between upper management and employees. It is a quality management practice and mechanism that serves to sustain employee empowerment and morale, while maintaining a vital effect on improving efficiency, productivity, growth, and corporate ethical standards
