Hi, Just to share my opinion.
I would follow the guidelines on the salary structure of your organization and pay him accordingly, even if the applicant has asked for a lower salary. The reason being:
1. Giving confidence to the new applicants that the company practices a fair and equal policy towards ER.
2. Avoiding any grievance on discrimination.
3. Avoiding any grievance on inequality, especially when you have colleagues who are performing similar or lower functions with higher pay than that person.
4. Building future trust between the employee and employer.
Basically, to ensure that everyone starts off on the right footing.
In some ways, I can agree with Ed. However, we cannot predict how the individual will react when they find out the truth about their pay. If they bring the matter up, then there is a resolution... but if they grumble and complain and badmouth at the back, the backlash can be great towards morale, confidence, and trust towards the organization, which, to me, is so hard to find these days.
As the saying goes, "There are two things you don't monkey around with a man... the first is his wife, and the second is his paycheck."
Hope this gives you another view. Have a good week.
Regards
