Show love to workers, as some may on entering office (4,5)
I believe the answer is:
kiss hands
'some may on entering office' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'show love to workers' is the wordplay.
'show love' becomes 'kiss' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to workers' becomes 'hands' (hand is a kind of worker).
'kiss'+'hands'='KISS HANDS'
'as' is the link.
Can you help me to learn more?
(Another definition for kiss hands that I've seen is " Accept senior office".)
