NASCO Group, Jos North, Plateau State, Nigeria. Recognizing the critical role of employee

well-being and productivity in organizational success, the research determined how different

work schedule namely fixed, flexible, and shift schedules impact various dimensions of job

satisfaction. A quantitative research design was employed, utilizing a structured questionnaire

administered to 150 employees of NASCO using a cross-sectional survey, Job descriptive

index (JDI), (Smith et al 1969) and Minnesota Satisfaction Questionnaire (MSQ). Weiss, et

al 1967). Data collected was analyzed using descriptive statistics (frequencies, percentages,

means, standard deviations) showing a significant difference in job satisfaction scores between

the two groups.

Employees on a fixed day schedule reported a higher mean job satisfaction

score (M = 4.21, SD = 0.68) than employees on a rotating shift schedule (M = 3.65, SD =

0.82). The t-test result was statistically significant (t (148) = 5.47, p < .001). The inferential

statistics (correlation and multiple regression analysis) ascertained the relationships and

predictive power between work schedules and job satisfaction, indicating a positive and

statistically significant correlation between work schedule flexibility and job satisfaction (r =

.482, p = .001), while rigid or unpredictable shifts contributed to lower satisfaction levels

with negative correlation between the number of hours worked per week and job satisfaction

(r = -.095). The findings are anticipated to provide valuable insights for NASCO management,

human resource practitioners, and policymakers in designing optimal work arrangements

that enhance employee well-being, reduce turnover, and improve organizational performance

within the Nigerian manufacturing context.
