SSS: Private Company Salary And SSS Benefit

Iba pa po ba yung makukuha mong salary from your employer (private company) during your 4 month maternity leave sa SSS cash benefit na makukuha mo? Is it "4 months salary + sss cash benefit"? Or yung SSS cash benefit ang ipangsasahod sayo ng company during ML? Then ibibigay lang nila yung differential ng actual sahod mo sa loob ng 4 months? So ang makukuha lang po is "SSS cash benefit + salary differential"? Thank you!
