The multiple regression analysis showed combined influence of independent variables on the dependent variable job performance (F=191.106: P<0.05), for motivation, relative influence existed between salary (β = -0.058, p = 0.023), promotion (β = -0.091, p = 0.000) and job performance. While space availability (β = 0.322, p = 0.000), illumination (β = 0.474, p = 0.000) had positive relative influence and heat (β = - 0.177, p = 0.000) negative relative influence on job performance for work environment.
