For some people, not having regular obligations can lead to boredom and a sense of loss of purpose. If you are very dedicated to your work, it may play a large role in your life, and not working may leave you with a lot of extra free time, which can make some people feel restless. Boredom has the potential to lead to detrimental habits if the person in question does not know what to do with themselves. Going back to work, even just part-time, can help a retiree reestablish a schedule and fill their time with a productive activity. Additionally, part-time jobs can be ideal because they allow for a good balance between structure and leisure. By allowing for either familiar or new work, returning to a job can keep retirees busy and therefore generally in higher spirits.
