My mum works for a certain high street store and today they let someone work in the store who my mum says should be self isolating as she is a student at a school that has been closed for a few weeks for a deep clean because it has 2 coronavirus cases (a pupil and a teacher). It was the neice of the store manager. My mum and the other employees were told to leave if they didn't like it? AIBU to be furious at such unprofessional favouritism that could be potentially exposing my mum and others to coronavirus? They are surely risking spreading coronoviris to the stores staff and customers? Is there anyone my mum can complain to about this?
