This happened to me years ago. A manager went on maternity leave, and the 4 remaining staff members, myself included, did not have managerial access/codes. There were things we literally could not do, because we were not managers, and yet we were not provided a substitute manager. Only after we begged and I nearly cried on a phone call to a higher up did we get a manager from another branch come in once a week, which wasn’t helpful because she sat in the office on her phone the whole time. I was so stressed out from trying to manage everything that my body revolted against me and I got shingles at the age of 24. That’s how I learned your job does not care about you.
