Looking for a word...

Is there a more sophisticated term that means the same as 'short-handed' or 'short-staffed'?  Something to describe an office or company that doesn't have enough people to do all the work for whatever reason.  

I feel that there is a word, but I can't think what it is and the thesaurus isn't helping me.  ~.~

I could say the institution in question has 'insufficient personnel' but it doesn't really have the same 'feel' as what I'm looking for.  A 'staff shortage' isn't quite right either.

I want a term that, essentially, means that the office has an expected number of staff and they can't find enough people to meet that quota.

If it's an especially British term, that'd be even more fantastic.

Thanks in advance for any help!
