Human Resources should be consulted before making a verbal offer to an employee or prospective candidate.
Human Resources will compare equity internally and factor in the candidates experience to provide the hiring manager with a range or number that can be provided to the candidate.
When a current employee receives an offer from another employer, a retention offer may be possible, if deemed appropriate by Human Resources. A formal letter of offer from the competing organization must be provided to Human Resources.
If a change in compensation is within range for the position and does not cause equity issues, Human Resources may approve a retention offer.
If the department cannot produce an external offer letter, then a retention offer cannot occur. Instead, the department will have to request a promotion, reclassification, market adjustment, or in-range salary increase.
