Office worker maybe left eastern place of worship (6)
I believe the answer is:
temple
'place of worship' is the definition.
(temple is a kind of place of worship)
'office worker maybe left eastern' is the wordplay.
'office worker' becomes 'temp' (a temporary office worker).
'maybe left' becomes 'l' (common abbreviation. I am not sure about the 'maybe' bit.).
'eastern' becomes 'e'.
'temp'+'l'+'e'='TEMPLE'
Can you help me to learn more?
(Other definitions for temple that I've seen before include "House of worship" , "'Shirley ..., child movie star (6)'" , "Delicate spot on the head" , "centre of interest?" , "One of two archbishops" .)
