This is the most viable option for enhancing savings for those nearing retirement. However, there is a caveat. Even though you may wish to continue working, there is no assurance that you will be able to do so.
The ability to continue working may depend on the nature of your individual circumstances, among which include the following: Whether your employer will allow you to stay on with the company as you approach retirement; ill health and family responsibilities that may prevent you from working; and whether layoffs may affect your work status.
Because of these uncertainties, it is prudent to have alternative plans to help you bridge gaps in your retirement savings.
