Human groups tend to repeat behavior patterns. Therefore, it may be common that in our company, we have a slightly grumpy person, another who struggles to get started in the morning because they are very sleepy, or the one who is always hungry and thinks any moment is good to go to the vending machine to refuel. Not forgetting the one who sends emails non-stop or the one who is constantly making jokes.
Surely you have identified some of these profiles or have been inspired to find some behavior in your organization that is characteristic of a person. You could give them, for example, a commemorative plaque as an award with an engraved phrase explaining what makes them different. The idea would be to highlight representative aspects of each person so that everyone has fun and enjoys a relaxed time.
It's a detail made with tact and empathy, of course, choosing people and their qualities that can make everyone smile, especially the protagonist. If you have doubts about whether the person might feel offended, it's better to think of something else. The best is to do it with sincerity and affection, so everyone perceives it as an affectionate joke among colleagues to have fun and have a good time. If you are not sure if a particular award is appropriate, consult your office colleagues. Maybe you can create a creative team to design the awards and make it an even more collaborative activity.
