Sales achievement of PT.Uniplastindo Interbuana Ciawi Plant in 2021.An average of 89% every month and total sales only reached an average of IDR 25,729,769 every month.The failure to achieve this target is thought to be due to the low performance of employees at PT.This is thought to be due to an uncomfortable work environment and a leadership style that has different characteristics and temperament, resulting in employees experiencing symptoms of work stress and causing the company to suffer losses as a result of not achieving targets determined by the company.
The aim of this research is to determine and analyze simultaneously and partially employee performance, physical work environment, leadership style and work stress at PT. Uniplastindo Interbuana Ciawi Plant.Based on this description, an uncomfortable work environment, a leadership style that has poor characteristics and temperament and work stress resulting from pressure imposed by the company, are thought to influence employee performance.If this problem is left unchecked, the impact will affect the continuity and goals the company wants to achieve.Therefore, researchers need to conduct research with the title "The Influence of the Physical Work Environment, Leadership Style and Work Stress on Employee Performance at PT. Uniplastindo Interbuana Ciawi Plant".
