A more throughout explanation: “Optional retirement” refers to a retirement arrangement where an employee has the choice to retire from their employment at a certain age or after completing a certain number of years of service, rather than being required to retire. This term typically refers to a situation where an employee has the option to retire early, usually with reduced benefits, before reaching the standard retirement age specified by their employer or a pension plan.
Example: In our company, employees have the option to participate in the optional retirement plan.
