Well.....as the wife of someone is sales, I do agree with recognizing those who help you out throughout the year. My husband tries to do that with all of his support team (which is quite large). However, if we ever found out any of those people were disappointed or ungrateful of the gift because it wasn't large or grand enough, I guarantee you that would be the last year they would get one.
Gifts, especially in the workplace, should be simply appreciated and not expected....and certainly shouldn't be looked down upon because you feel it wasn't good enough. Personally, it would mean so much more to me to have this person raving about my abilities and how much they love working with me......some people would love to get that kind of verbal recognition.
