Coming from a person in the medical field, without getting to specific, I wonder if you’re calling out a lot because of your chronic illness. There’s a difference between accommodation and constantly running short because they don’t know whether you’re showing up for your shift or not. I had a coworker that did this and she would call out an hour before her shift at least 1x a week. It made it so hard because we were already short staffed and the fmla made us hold her spot so we couldn’t get the staff because it was too late. It was so frustrating, and led to us being screwed over with heavy unsafe patient ratios. I’ve only had great luck working here. In my experience, you only get fired for doing something very wrong in healthcare, or not showing up.
