fireworks

I'm a little stuck... Click here to teach me more about this clue!

'in display of temper' is the definition.
I can't judge whether this defines the answer.

'female anger is employed' is the wordplay.
'female' becomes 'f' (abbreviation).
'anger' becomes 'ire' (ire is intense rage).
'is employed' becomes 'works' (I've seen this in another clue).
'f'+'ire'+'works'='FIREWORKS'

Can you help me to learn more?

(Other definitions for fireworks that I've seen before include "rockets, perhaps" , "Pyrotechnics" , "Display on November 5th etc" .)

I've seen this clue in The Telegraph.
