I work at a certain sandwich chain that boasts about how Fresh the food is. I'm also chronically ill and have tried to work with my manager multiple times, begging for time off to attend Dr's appointments that I need. I'm still called in to my job almost every day off I get, and even when I'm not there I'm expected to be 'on call' to help coworkers if they have questions about something. I desperately want to quit and get another job but I'm not very qualified for anything but hard labor… and as I mentioned, I'm chronically ill. I don't know what to do, any advice?
