This research method uses quantitative methods with a descriptive approach. The data collection methods used are primary data and secondary data. The sampling technique in this research used the saturated sample, namely 60 respondents. Data analysis used the SPSS version 29 program.

Partially testing the hypothesis for the Reward variable (X1) obtained a value of tcount > ttable (2.253 > 1.671) and a significance value of 0.028 < 0.05. This means that Reward (X1) has a significant effect on Employee Performance (Y). Partially testing the hypothesis for the Punishment variable (X2) obtained a value of tcount > ttable (1.927 > 1.671) and a significance value of 0.059 < 0.05. This means that punishment (X2) has a significant effect on employee performance (Y). Simultaneous hypothesis testing obtained a value of fcount > ftable (10.593 > 3.162) and a significance value of 0.000 < 0.05. So it can be concluded that Reward (X1) and Punishment (X2) simultaneously have a significant effect on Employee Performance (Y).
