Check condition and put back to work (9)
I believe the answer is:
reinstate
'put back to work' is the definition.
'check condition' is the wordplay.
'check' becomes 'rein' (both can mean to control or limit).
'condition' becomes 'state' (the state something is in).
'rein'+'state'='REINSTATE'
'and' acts as a link.
(Other definitions for reinstate that I've seen before include "Restore to a former condition" , "Put back in place" , "Put back into office" , "Re-establish" , "Restore to former post" .)
