Discrimination in Application of Single or Family Status in Determinin

[Guest BKing]

My company offers a benefits package that allows employees to select the various types of coverage they want for medical, dental, life insurance, etc. It includes the option to receive up to a specified amount in cash back at the end of the year. They calculate the number of benefit credits you receive based on your family status, age and salary. I am divorced with a dependent child and did not elect family medical insurance coverage, but did select family coverage in all other areas of the plan. I was told that since I elected single medical coverage, my benefit credits were recalculated as a single instead of family status. This recalculation did not occur with married employees who did not choose medical coverage for their dependents. Is this legal?
