Could be, could be...
I know we (my company) experience a few hiccups in production, but more impact is actually in the distribution channel. The production jobs are more lucrative and sought-after whereas distribution (basically moving boxes around and picking product) is not as highly paid and more likely to be affected. I think there's been some talk about providing some kind of a "return" bonus for workers who come back after the New Year and work for x more days... Not sure if that's been implemented though. The effect is, on the whole, pretty minimal.
