See mum circulating among workers providing diversions (10)
I believe the answer is:
amusements
'diversions' is the definition.
(amusement is a kind of diversion)
'see mum circulating among workers' is the wordplay.
'circulating' is an anagram indicator.
'among' means one lot of letters goes inside another.
'workers' becomes 'ants' (I've seen this before).
'see'+'mum'='seemum'
'seemum' with letters rearranged gives 'museme'.
'museme' inserted within 'ants' is 'AMUSEMENTS'.
'providing' acts as a link.
(Other definitions for amusements that I've seen before include "Fairground rides" , "Diversions" .)
