The Influence of Teamwork and Work Discipline on the Performance of Alfamart Employees in the City of Medan

Abstract

This study aims to analyze the effect of teamwork and work discipline on employee performance at Alfamart in Medan City. The background of this research stems from the phenomenon of declining employee productivity caused by lack of collaboration between employees and inconsistent work discipline, especially in the modern retail sector. This research uses a quantitative approach with an associative research design. The population of this study is all Alfamart employees in Medan City, and the sample was taken using purposive sampling technique with a total of 100 respondents. Data collection used a questionnaire with a Likert scale that had previously been tested for validity and reliability. The analysis technique used is multiple linear regression analysis, coefficient of determination test (R²), and hypothesis testing (t-test and F-test) with the help of SPSS version 26. The results of this study indicate that: (1) teamwork has a positive and significant effect on employee performance with a t-value of 4.872 and a significance of 0.000; (2) work discipline has a positive and significant effect on employee performance with a t-value of 5.341 and a significance of 0.000; and (3) teamwork and work discipline simultaneously have a positive and significant effect on employee performance with an F-value of 48.763 and a significance of 0.000. The coefficient of determination (R²) value is 0.608, meaning that 60.8% of the variance in employee performance is explained by teamwork and work discipline variables, while the remaining 39.2% is influenced by other variables not included in this study. It is recommended that Alfamart management pay more attention to building effective teamwork and enforcing consistent work discipline as a strategic step to improve overall employee performance.
