Final answer:
An HR manager should address an employee's concern about pay equity by performing a job evaluation and providing a pay increase if there is an inequity.
Step-by-step explanation:
An HR manager should address an employee's concern about pay equity between his job and the job of another employee with a similar role by performing a job evaluation of the employee's position.
By conducting a job evaluation, the HR manager can objectively assess the responsibilities, skills, and requirements of both roles to determine if there is a legitimate reason for the pay difference. This evaluation can help identify any potential inequities and allow the HR manager to make informed decisions about addressing the concern.
If the job evaluation reveals that there is indeed an inequity, the HR manager should provide a pay increase to eliminate the discrepancy and ensure fair compensation.
