This research investigates the influence of both internal and external work demands on the decision-making capabilities of personnel working in the Nationality, Passports, and Residence Affairs department of the Ministry of Interior in Bahrain. The study offers a thorough comprehension of how job demands impact decision-making processes by examining both aspects of these elements. The results demonstrate significant associations between job-related stress and challenges in making decisions, highlighting the need of specific interventions to improve employee contentment and productivity. A quantitative research methodology was used, using a structured questionnaire to collect data from a sample of 291 workers. The survey consisted of comments pertaining to both internal and external work demands, as well as decision-making procedures. Participants' responses were assessed using a five-point Likert scale. The data underwent statistical analysis to ascertain the correlations between the variables. The study showed significant relationships between internal pressures and decision-making (mean = 4.5, SD = 0.6) and between external pressures and decision-making (mean = 4.6, SD = 0.5). The confluence of these demands has a substantial influence on decision-making capacities, as workers report heightened challenges in making judgments when confronted with high-pressure circumstances. The study’s findings indicate that both internal and external job demands have a negative impact on decision-making capabilities. Suggestions include employee participation in decision-making, enhancing the work environment with contemporary technology, offering assistance and training, and undertaking further study on work pressures in various organizational settings. These measurements may optimize decision-making processes, promote satisfaction among workers, and enhance organizational performance.
