An annuitant is a person who is entitled to receive benefits from an annuity.
[1] The payout benefits for an annuitant are based on the person's life expectancy.
Often a maximum number of hours per year which the annuitant may work is specified.
[2] For instance, the State of California has posted annuitant guidelines.
[3] The rehiring of retired employees often allows agencies to benefit from the experience of retired employees who may be relied upon to share their experience and training with new hires, or to supplement or "bridge" areas where person power is needed but not currently affordable.
