The inferential statistics part analyzes the effects of company rewards factor on employee work’s efficiency by using t-test, f- test, multiple regression analysis (MRA).

The result of this study the occupational stress factors about the organization structure have a significance value of .011 which is acceptable. On the other hand, Occupational stress factors intrinsic to the job, roles in an organization, career development, and relationships at work have a significance level at .359, .725, .098, .976 respectively which are unacceptable as the significance values are higher than 0.05. Moreover the effect of the occupational stress factors (Intrinsic to job, Role in an organization, Career development, Relationship at work, Organization structure) on employee’s work efficiency (quality, quantity, times, costs) at ABC company shows the occupational stress factors have an effect on employee work efficiency. But when analyzed by individual variables, nine of the factors have significance levels lower than 0.05 which can be described as follows: Employee’s work quality: Intrinsic to job, career development, relationships at work factors have a significant effect on employee's work quality with the significance levels of .023, .006 and .030 respectively. Employee’s work quantity: Career development and Relationships at work factors have a significant effect on employee's work quantity with the significance level at .000 and .010 respectively. Employee’s work time: Career development, Relationships at work and Organization structure factors have a significant effect on employee's work time with the significant level at .023, .000, and .013 respectively. Employee’s work costs: Only the organization structure factor has a significant effect on employee's work costs with the significance level of .011. From the result, it can be interpreted that the difference of occupational stress factors (Organizational structure, Role in an organization, Intrinsic to job, Relationships at work, Career development) have an effect on employee’s work efficiency (quality, quantity, times, costs) during the period of ABC’s company merger and acquisition
