I have a lot of coworkers out and in result my manager keeps asking only me to cover 5-3. I am the youngest one in my department so I’m assuming they’re assuming i can do it and handle it. My other coworker is 20 years my senior and was not asked to come in earlier or stay later and neither was the per diem that is scheduled. Is this fair? I have a lot of health issues going on that totally get exacerbated when I work more than 9 hours. I told my manager I’m available to do a 5-2 but she doesn’t seem pleased about that.
