Applaud workers supporting strike (4,5)

I believe the answer is:

clap hands

'applaud' is the definition.

'workers supporting strike' is the wordplay.
'workers' becomes 'hands' (hand is a kind of worker).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'strike' becomes 'clap' (clapping is a kind of striking).
'hands' put after 'clap' is 'CLAP HANDS'.

I've seen this clue in The Guardian.
