i work at kroger as a full-time pharmacy technician, and i am scheduled for laparoscopic hernia repair in little over a month

i've applied for short term disability with metlife/kroger. from what i understand the doctor typically does two weeks' leave for this surgery but i will be given work release at my post-op followup two weeks after surgery. and i was told its possible i could need more time off, but i dont know.

at our job technically we request off three weeks ahead but the schedule is made beginning two weeks in advance. i dont want to request off longer than i need if i wont get paid for the extra time, altho i admit i'm excited about being off work. i have requested off for three weeks at this time but i dont know how this is going to work. will i be paid for this? i'm still waiting on a packet in the mail and a phone call
