Analysts here only half in humour for work (6)
I believe the answer is:
labour
'for work' is the definition.
(labour is a kind of work)
'analysts here only half in' is the wordplay.
'analysts' becomes 'labor' (I am not sure about this - if you are sure you should believe this answer much more).
'here' becomes 'UK' (the clue is from a British publication).
'only half' indicates taking half.
'in' is an insertion indicator.
'uk' cut in half is 'u'.
'labor' enclosing 'u' is 'LABOUR'.
'humour' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for labour that I've seen before include "See 1" , "Painful time" , "Donkey-work" , "Hard work, party" , "Shakespeare: 'Love's ...... Lost'" .)
