Nope, never. I've worked for 7 major corporations since I graduated from college and not one of them had a Christmas bonus policy.

One company I worked for did give us what we called 'boxing day' where we received an additional 35% off our purchases (over and above our normal employee discount of 50%). This meant that we were getting a 67.5% discount for one day. It made shopping for Christmas presents REALLY easy! ;-)
