The paper aimed to examine rank-and-le employeesâ€™ organizational commitment and the effectiveness of a holding company by assessing the level of agreement of the dimensions and variables. A quantitative technique engaging a descriptive research method was used in the study. The study applied Slovinâ€™s formula, with 92 rank-and-file employees responding, and the data collected were analyzed using weighted mean and descriptive equivalents. The findings revealed that normative commitment has the most dominant dimensions perceived by the rank-and-le employees constituting the overall mean of organizational commitment with a descriptive match of â€˜agree.â€™ Additionally, teamwork and direct manager gained the top two highest average weighted mean with a descriptive equivalent of â€˜agree,â€™ resulting in the core variables that constitute organizational effectiveness. The researchers concluded that normative commitment that has had the most direct impact on the holding companyâ€™s organizational commitment had stimulated teamwork and a leadership style that has operated as a cultural scaffold for building strong competitive advantage and effectiveness. Over and above that, the study suggested that nurturing and sustaining activities that will bring to light the employeesâ€™ shared vision and goals aligned with the organization will help buoy the level of the organizationâ€™s moderate level into a high level of organizational commitment and effectiveness.
