I work in a large DIY store which is still open, but I am concerned that being type 2 diabetic I am in a high risk group when it comes to Covid 19. I did ask my manager if I could stay at home and was told that I could take un-paid leave, but that as my diabetes is under control, the company does not class me as high risk. Does anyone know what my rights are? I can't afford to take un-paid leave, but I really don't like having to go to work and put myself at risk.
