when you boss kindly give you a box chocolates, for you efforts over the year.
Already no issues with accepting end if year work gifts in my area, because that's all it is, a thank you gift for your efforts over the year. However, too give a gift in return to your boss or non witness clients for the years work, well this would not to done, because this could be viewed as a Christmas related gift and we wouldn't want anyone to be stumbled.
