The achievement of high organisational productivity in today’s competitive environment must take into account the necessity of motivating and inspiring the workforce through a strong reward system based on cultural expectations that demand the best from the workforce in terms of performance commitment, dedication, and loyalty. All nations, including those in transition and developing regions, are cognizant of the crucial responsibilities that multinational corporations play in economic development, as evidenced by the existence of these corporations and their subsidiaries. The study’s goal was to evaluate how the cultural factor affected how satisfied employees were with how multinational corporations managed their human resources. Six (6) chosen multi national corporations in Lagos State make up the study population. While purposive sampling approaches were employed to deliver the study instrument to a sample of 1200 respondents, of which 1000 returned used, convenience sampling procedures were utilised to choose the suitable Corporations. Data collection was done using a questionnaire with a likert scale structure, and both the face and content validity were properly adjusted by a specialist for the study’s needs. The constructs’ respective Cronbach Alpha reliability coefficients lie between 0.78 and 0.86. For the data analysis, descriptive and inferential statistics were also employed. The study found that, with regard to the cultural dimension effect, training and development practises have positive, substantial effects on employees’ satisfaction among nationals in MNCs. The study suggested that in order to establish, maintain, and sustain a stable human resources management practise for the successful operation of the subsidiary in their particular environment, the management of Multi National Corporations should have an understanding of the cultural dimension and the environments in which they operate. Additionally, has a solid understanding of the nation’s cultural reward system, which inspires workers to be dedicated to the goals of their organisations.
