Retaliate and down tools, gaining support (6,4)

Ross

I believe the answer is:

strike back

'retaliate' is the definition.
(synonyms)

'down tools gaining support' is the wordplay.
'down tools' becomes 'strike' (I've seen this before).
'gaining' means one lot of letters go next to another.
'support' becomes 'back' (to back is to support or endorse).
'strike'+'back'='STRIKE BACK'

'and' acts as a link.

I've seen this clue in The Irish Times.
