ABSTRACT:- This study examined the effect of organizational stress on productivity of employees among selected manufacturing companies in south-south, Nigeria. Survey design was used and questionnaire was the major instrument of data collection, which was administered on one hundred and twenty-seven (127) employees of six (6) manufacturing companies. Two (2) variants of organizational stress (role ambiguity, and work-family interaction) and two(2) employees’ productivity measures (quality of work and quality of product) were employed.  Data obtained were assessed using descriptive (Cronbach alpha, mean, standard deviation, kurtosis, skewness and Pearson correlation) and inferential (multiple regression) statistical tools.  Findings of the study indicated that role ambiguity (F=12.88; p=0.0000) and work-family interaction (F=22.07; p=0.0000) negatively and significantly affect the productivity of employees. The study recommended that management should incessantly carry out stress audits to reduce the stress level, particularly with the role(s) assigned to employees.  Again, management should encourage employees to spend more time with their family members, by reducing work stress limiting work-family interaction.
