'plea to stop pulling' is the definition.
I can't judge whether this defines the answer.

'pieces of a fly' is the wordplay.
'pieces' indicates anagramming the letters (I've seen 'pieces of' mean this (I've seen this in other clues)).
'of'+'a'+'fly'='ofafly'
'ofafly' anagrammed gives 'LAYOFF'.

'to' is the link.

Can you help me to learn more?

I've seen this clue in The Irish Independent.
