Applying Big Data with fuzzy DEMATEL to discover the critical factors for employee engagement in developing sustainability for the hospitality industry: Multi-Criteria Decision Making/Group Decision Making

The hospitality industry is one of the fastest-growing industries in the world. The growth of this industry has been accompanied by issues of sustainability development. Employees expect firms to have the ability to address their negative impacts on the environment and society. However, firms are generally unable to reach such expectations due to an inability to acquire feedback from employees, which leads to employee dissatisfaction. In addition, there has been a lack in the theoretical linkage between employee engagement and sustainability development. Thus, this study determines the critical factors of employee engagement based on big data (using social media and quantitative and qualitative data) and integrates such data by using decision-making tests and laboratory evaluation methods to identify these interrelationships. The findings reveal that sustainability development can be enhanced through aggressive employee engagement, which also can generate a positive influence on economic performance. A detailed discussion is also presented.
