This research was conducted using a causal associative quantitative approach. The sample used was all company employees, with a total of 38 people. The research results show that work ability has a positive and significant effect on employee performance. This is shown by the T-count value of3.756 which is greater than the T-table 1.685, and the P-Value value is 0.000 which is smaller than 0.05. The regression coefficient shows that if work ability is increased by 1 unit, employee performance will increase by 0.931 units assuming other variables remain constant. Apart from that, the results of the determination test show an Adjusted R Square value of 0.221 or 22.10%, which indicates that work ability has a low influence on employee performance, while the remaining 77.90% is influenced by other factors that have not been studied. Thus, partially, work ability has a positive and significant effect on employee job satisfaction at the Binjai City Tourism Office. This identifies that, meaning, improvements in employee work abilities can contribute to improving employee performance.
