Analysis of the data in this study using multiple linear regression analysis assisted by a computer program SPSS for Windows. The results showed that simultaneously the F test resulted in an Fcount of 1339.803 with a significant level of 0.00. Because Fcount 1339.803> Ftable 3.22 and the significant probability is much smaller than 0.05, namely 0.00 <0.05, the regression model can be said that the work environment and work motivation simultaneously have a positive and significant effect on employee performance. . The results showed that partially the work environment tcount 1.259 0.05, meaning that partially work environment variables did not have a positive and significant effect on employee performance.
