Hello! I work for a private university. Our 403b match is different based on age. If you are under the age of 35 and have worked less than a certain number of years you are eligible for 4% (once you complete a certain number of years you're eligible for the full match). If you are over the age of 35 you are automatically eligible for 8%. Is it legal to create that type of rule? Seems like it favors employees over the age of 35 - who more than likely are also making more money than the younger employees.
