Leaving home, trainees worked extra long weekend (6)
I believe the answer is:
easter
'extra long weekend' is the definition.
The definition and answer can be both related to time as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'leaving home trainees worked' is the wordplay.
'leaving' indicates named letters should be taken away.
'home' becomes 'in' ('he's home' can mean 'he's in').
'worked' is an anagram indicator.
'trainees' with 'in' removed is 'traees'.
'traees' with letters rearranged gives 'EASTER'.
Can you help me to learn more?
(Other definitions for easter that I've seen before include "Church festival" , "Time to celebrate" , "Snug retreat" , "Christian feast of the Resurrection" , "A terse sort of Spring festival?" .)
