'strikes' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps you can see an association between them that I don't see?

'prevent errand boys' is the wordplay.
'prevent' becomes 'stop' (stopping is a kind of preventing).
'errand boys' becomes 'pages' (page is a kind of errand boy).
'stop'+'pages'='STOPPAGES'

'having' acts as a link.

Can you help me to learn more?

(Other definitions for stoppages that I've seen before include "industrial action" , "Amounts deducted from wages" .)
