Brand given to group of workers, temporary (9)
I believe the answer is:
makeshift
'temporary' is the definition.
(similar in meaning)
'brand given to group of workers' is the wordplay.
'brand' becomes 'make' (synonyms).
'given to' says to put letters next to each other.
'group of workers' becomes 'shift' (I can't explain this - if you can you should give a lot more credence to this answer).
'make'+'shift'='MAKESHIFT'
Can you help me to learn more?
(Other definitions for makeshift that I've seen before include "this'll do for now" , "What 11 [SEAMSTRESS] might do" , "temporary expedient" , "not meant to last" , "Temporary or improvised substitute" .)
