Bah humbug! You might not be decking the halls this year in the office, according to a new survey by staffing firm Office Team. Over half of senior managers interviewed for the survey said they aren't planning any office holiday parties this year.  The economy is one reason for the lack of holiday cheer, but legal repercussions and the prevention of unwanted surprises (Wonder what those are?) were sited as major reasons for the cancellations.
