Sending a gift card to a former boss as a gesture of thanks can be a nice and thoughtful gesture, especially if they had a positive impact on your life or career. However, there are a few things to consider before doing so:
Relevance: If it has been years since you last interacted with your former boss, they might find it surprising or even awkward to receive a gift from you out of the blue. Consider whether the timing and context of the gift are appropriate.
Intentions: Be clear about your intentions. If you are sending the gift card just to express gratitude and don't intend to reestablish contact, it's essential to be upfront about that. Otherwise, your former boss might interpret the gesture as an attempt to reconnect or start a conversation.
Professionalism: Keep the gift card and message professional, avoiding anything too personal or sentimental, as you haven't kept in touch for a long time.
Workplace Policies: If your former boss still works for the same company or organization, make sure that their workplace policies allow them to accept gifts from former employees.
Tone and Perception: The tone and value of the gift card matter. A small token of appreciation is generally more appropriate than an extravagant gift.
If you decide to go ahead with sending the gift card, you can include a brief note expressing your appreciation for the positive impact they had on your career or how their guidance helped you. Make it clear that you don't expect anything in return and that you simply wanted to say thank you.
Remember that every situation is unique, and your relationship with your former boss will also play a role in how they perceive the gesture. Use your judgment and consider the circumstances before sending the gift card.
