Polish workers getting increase (7)
I believe the answer is:
beeswax
'polish' is the definition.
(I've seen this before)
'workers getting increase' is the wordplay.
'workers' becomes 'bees'.
'getting' says to put letters next to each other.
'increase' becomes 'wax' (waxing is a kind of increasing).
'bees'+'wax'='BEESWAX'
(Other definitions for beeswax that I've seen before include "Substance used to build honeycombs" , "Output of buzzers" , "Polish ingredient" , "Honeycomb material" , "Furniture polish" .)
