Giving birthday gifts to leaders is very skillful. First of all, you need to understand the age of the leader, because the gifts given by people of different ages are not the same. Here are some suggestions for you, hoping to give you some inspiration:
1. Give the leader a birthday gift he likes according to his personality and hobbies. Because he is the leader of your department, you must know some of his hobbies. For example, he likes to drink tea, so you can give him some high-end tea sets, which are very good gifts.
2. Choose gifts of different values according to the leader's taste. Because some leaders are not very interested in things that do not match their values. If the gifts are too ordinary, they will disgust the leaders. So you must give birthday gifts that match their tastes.
3. Give birthday gifts of appropriate price according to your income. Because giving gifts higher than your income level will embarrass the leader and finally refuse your gift. Giving gifts below the income level will make the leader think you are stingy and ignorant, leaving a bad impression, so you must pay attention to the preciousness of the gift.
I believe that after reading the above suggestions, you should already have a very suitable birthday gift in mind. I hope your work goes well!
