To wish someone a happy retirement, use messages that thank the person for his or her contributions in the workplace, wish him or her luck on future endeavors and end with a farewell. People can put this message in a card that everyone at the office signs or in individual cards.
Many companies purchase a gift for the retiree, or coworkers get together and all pitch in to buy a gift. A gold pocket watch is a classic gift idea, and it may or may not be engraved. Other popular options include a new cellphone, a gift that represents the retiree's favorite hobby or a novelty clock.
