Current time could be time to take on staff (11)
I believe the answer is:
recruitment
'time to take on staff' is the definition.
(period in which to recruit new staff)
'current time could be' is the wordplay.
'could be' is an anagram indicator.
'current'+'time'='currenttime'
'currenttime' is an anagram of 'RECRUITMENT'.
(Other definitions for recruitment that I've seen before include "Staff engagement" , "Action of finding workers" , "Taking on people" .)
