We currently offer vacation accrual rates based on length of service with some exceptions for corp title and/or position. What are the guidelines we should follow when offering a higher accrual rate based on position? Should the exception criteria be formally outlined and published to associates or can we just maintain as an internal HR process. Most surveys only list accrual ranges by service and omit position criteria but I know that many employers adjust accruals for certain levels or grades. Any resources that can be provided would be most appreciated.
