Hi!
We did not have any financially-driven layoffs last year, but we did decrease raises and eliminate bonuses and as a result, had the same hesitations you are experiencing now. We decided to pare back our party, held it in house rather than the usual hotel ballroom, and spent about half as much money as a result. Of course there were grumblers, but for the most part our employees appreciated the effort we made to celebrate without breaking the budget. Good luck with your planning!
