Took leave of office

[tufguy]

"Yesterday he took leave of the office early (he came back home early taking leave), office finishing time is 6 PM but he left at 5 PM".

"Yesterday he took half day leave".

Please check.

 

[bhaisahab]

"Yesterday he left the office an hour early."

 

[Rover_KE]

'Yesterday he took a half-day leave of absence.'

The first doesn't work for me, and the second sounds excessive if he left an hour early. I would use Bhaisahab's sentence for this situation.
