Job Satisfaction is from the point of view of the employee , whereas, Employee Satisfaction is from point of view of the company / employer.
Both topics are more or less interrelated and complimentary to each other.
In case of Job Satisfaction , the objectives should be set to know intrinsic details of Job Performed and factors affecting the same (internal and external)
In Employee Satisfaction (for which job satisfaction is an important element) , objective should be set with a wholistic approach, taking into the account, entire factors influencing the employee to stay/work in the company.
Hope you have some clarity now
