Abstract
Prosocial behavioural management strategies, commonly viewed as voluntary actions intended to support others or contribute positively to the organisation, remain essential for strengthening employees' sense of commitment, collaboration, and overall effectiveness at work. This study investigated how prosocial behavioural management strategies relate to workforce productivity in selected manufacturing firms within a nascent economy. A survey design was employed, using a five-point Likert-based structured questionnaire to obtain data from 291 respondents out of an overall workforce of 1,072. Yamane's (1967) formula with a 5% margin of error was used to determine the sample size, and quota allocation was used to guarantee equitable representation among the firms. Convenience sampling was adopted to facilitate accessibility and respondent participation. While reliability was confirmed using Cronbach's Alpha, with all variables recording values over 0.70, the validity of the instrument was demonstrated through content and construct assessments. Using SPSS version 20, descriptive statistics, Spearman's Rank Correlation, and simple regression were used to examine the data. Conscientiousness and affective commitment were found to be significantly positively correlated. This suggests that individuals who are self-disciplined, responsible, and intrinsically motivated tend to have greater emotional attachments with their businesses. The study concluded that conscientiousness contributes meaningfully to employee performance by fostering trust, cooperation, and affective commitment within manufacturing environments. It recommends that management cultivate a supportive culture that rewards prosocial actions through empowerment initiatives, fair recognition, and ethical leadership.
