I believe sick pay doesn't have to be approved by the store just corporate.
In the past our HR ETL would just sit on it.
I have put in sick pay in the past and it was in my time card within 24 hours.
I called off sick in a recent month on at roughly 9:00 AM.
My PTO sick pay was added the next day at roughly at 4:00 AM though it was only 4 hours.
Also screen shot it because it disappears in the app quickly.
