Roadmap to retirement: When your employer or plan changes. A private retirement plan can change its rules or terminate at any time. These changes can occur for a variety of reasons: during company mergers, to streamline plan administration, to improve plan features, or to reduce costs.
To retire is to withdraw from an active working life, and for most retirees, for the rest of their lives. Retirement is different for everyone. Age wise, it can be during any normal working year in adulthood. Some may choose to semi-retire by gradually decreasing their work hours as they approach retirement.
