Best way to go about this?

Hey guys, I started 2023 was thrown in the cooler as a A.M. 3-1130 stocker been there ever since! I get to finish my last 2.5 hours of the shift in Tire shop. I feel I have a good gig. But recently, I hurt my shoulder, a “slap” tear. I had it looked at by the doctor, and was given a Cortizone shot, and he told me limited mobility lift at chest height and take it easy. (Nothing on paper for work) We all know light duty cannot be done as a Costco stocker . Especially in the cooler. Everything is overhead lifting. From other reading, I’ve done. Costco doesn’t want me to come back, unless I have full clearance. I’m only two years in so as far as frontend seniority. I’m at the bottom of the list. I don’t assume I’d get a permanent door spot or office job. Iv heard they would make me fold clothes At night So I’ve been working with this injury for probably about a month and a half now and just over the Fourth of July weekend iv called out for two days. could I get disability and how long could I be out for ??

Noholiday pay for me!!! Oh well health is wealth right??????

I’m not gonna go to work in deteriorate my body anymore !
