Some companies offer employee discounts as part of their benefits packages.
Employees receive discounts when buying or using company products or services and often reap discounts from partnering businesses. The Coca-Cola Co. and Kellogg Co. each offer employees a wide variety of discounts and convenience programs that include on-site perks such as dry cleaning and credit union memberships.
A number of retirees pick up post-retirement jobs at theme parks, and they use their employee discounts to treat their grandchildren, says Epstein.
Employment after retirement makes sense for many other reasons. Riggs and Birnbaum say they'll probably continue to work because they enjoy remaining engaged.
"I still have plenty of energy to be challenged. I always thought when I would retire, I would retire," says Riggs. "And getting a better feel of being totally retired, I really decided I was not ready to give up on work just yet."
Birnbaum agrees, and says that for many retirees, sitting on the couch watching television while their worlds grow "smaller and smaller" is simply not an option. And why should it be, when the benefits of staying employed can be so enriching?
