The research goals were to explain the simultant and partially influence of physical (X1) and non-physical (X2) to work stress (Y). Research type is explanatory research method with quantitative approach. Population are employee of PT PLN (Persero) at Malang Service Area, East Java Distribution with seventy-five employee has picked as research sample. The result are the changes of working stress (Y) variable could be explained by physical (X1) and non-physical (X2) working environment variable as 34,6 percent and the balance about 65,4 percent remainder are affected by different factor that doesn't covered by the research. While evaluating hypothesis, there are significant effect simultaneously and partially from physical and non-physical working environment on employee work stress variable. Working environment variable as partial have negative effect that mean if there is better working environment will reduce employee's work stress. Working environment give sicnificant effect on employee's work stress. This is shown by the regression coefficient physical work environment and non-physical work environment in a sequentially of -0,224 and -0,483 along with significant phisycal working environment value about 0,007 (0,007<0,05) and non-physical working environment about 0,009 (0,009<0,05).
