How about using a bee stamp, (I know there is one in the Daisy set, probably several others, as well). The inside sentiment could be something like, "From all of us worker bees." If your boss is a gal, you could address it to the 'Queen Bee.'
PS - I lived in McKinney for awhile several years ago. My hubby and I were married there! I really miss the shops on the square!
