This research aimed to (1) study the differences in personal factors affecting work performance,
(2) study the levels of work–life balance and work performance, and (3) analyze the influence of work–life
balance on the work performance of administrative officers under the Office of the Attorney General
Region 5. This study employed a quantitative research approach. The population consisted of 484 individuals,
and the sample size was determined using Yamane’s formula, resulting in 250 participants selected
through purposive sampling. The research instrument was a questionnaire that had been tested for content
validity, with the index of item-objective congruence (IOC) meeting acceptable criteria. Data were analyzed
using descriptive statistics, including frequency, percentage, mean, and standard deviation, as well as
inferential statistics, including independent sample t-test, one-way ANOVA, and multiple regression analysis.
The findings revealed that differences in monthly income significantly affected work performance, whereas
differences in gender, age, educational level, job position, and marital status did not significantly
affect work performance. Furthermore, work–life balance in the dimensions of work, intellectual, family,
and financial aspects had a statistically significant positive influence on work performance. In contrast,
time-related work–life balance had a statistically significant negative influence on work performance.
These findings reflect that the management of work–life balance in each dimension should take into
account their differing influences in order to appropriately enhance the work performance of public sector
personnel.
