What limitations have you faced when preparing Job evaluation?

Job evaluations faces many limitation as there is no standard list of factors to be considered for job evaluation. It lacks scientific precision. There is always a strong feeling among the workers that individual merit should be rewarded. It is presumed that jobs of equal worth will be equally attractive to the employees, but it is not true. If a job offers no prospects of a rise, while another job rated equal to it has bright prospects, the later will attract more people. Many times trade union regard job evaluation with suspicion because of the methods is not scientific and is difficult to understand. Sometimes wages fixed for job on the basis of it might not workers who can make more money else.
