A coworker who came back from vacation goes around and puts a small snack on each desk. A foreign coworker once asked, "What's the occasion?" It's not a birthday or a party, after all. ## Why do they hand out snacks? It's a way of saying, "Thank you for covering for me." In Korean workplaces, work is often shared among several people. So when I'm away from my desk, the coworker next to me answers my phone and takes care of my papers. Often it happens that way even without being asked. Just saying thanks feels a little insufficient, so people add a small gift. ## Is it something you have to do? No, it isn't. It's a common custom, not a rule. You won't get scolded if you don't do it. But a lot of people do it if they've been away for a long time. It's about showing your thoughtfulness, so it doesn't need to be expensive. If it's too expensive, the person receiving it may actually feel burdened. ## How can I do it too? Buy individually wrapped cookies or chocolates so that each person can have one. You can buy them on your trip, or at a convenience store or supermarket, which is fine too. It's even better if you attach a note with a line like "Thanks to you, I had a great trip." Some of your coworkers may have allergies, so check that the packaging lists the ingredients. For the person who directly took over your work, be sure to thank them in words as well as with the snacks.
