Depends on the length of leave requested, fleet, and seat.
From Mar 2012 SSC report (page 2-3):
Short-term Leaves
The company continues to offer short-term LOAs. As previously stated, this is made
possible by an MOU covering leaves that commence on or before May 30, 2012, allowing
short-term leaves up to 90 days with benefits. The response for the LOAs has been strong,
with requests ranging anywhere from seven days to three months. The company reported
they had to deny some leave requests due to manpower shortages.
