This study examined the influence of Expensed Human Resources Cost (HRC) on corporate productivity. Human resources have been identified as one of the main sources of competitive advantage by many organizations in today’s economy. This is true not only of knowledge intensive organizations, which are based on services and Intangible outputs, but also increasingly of more traditional organizations, both in the private and public sectors. However, human resources are still not recognized in the reporting mechanisms, despite an interest dating back to the 1960s in techniques such as human resource accounting (HRA). In other to investigate the above issues, the researcher gathered data from ten (10) companies listed in the Nigeria Stock Exchange (NSE) with the aid of a questionnaire using an expost facto design. The study revealed that expensed human resources (remuneration, protection and dismissal/ compensation) costs are important determinants of expensed human resources cost and does significantly influence corporate productivity. Conclusively, expensed human resources cost approach to corporate productivity measurement which have gained substantial attention and use in recent years provides further opportunities for utilization of human resource accounting measures. Finally, the study recommended that employment security should be seen as an important part of high performance HRM practices. Companies that provide their employees with job security signal a long-standing commitment to their workforce, whom in turn is more motivated to develop special skills and competencies that are valued by their company. Employees who perceive that their jobs are secure are also more likely to suggest productivity improvements and to take a more comprehensive and long-term view of their jobs and the company’s productivity.
