Oh wow....that's a real bummer considering you are having major shoulder surgery. And you are right....no lite duty. Perhaps there is something else you can do while healing before you return to the carts. Have you had a chance to talk to your manager? We have a wonderful grocery store here. They treat their employees like family. It always feels good to go shopping and see our "friends".

Isn't your surgery and care covered by Worker's Compensation?

Good luck. Give it a try......let them know what you are facing.
