Should I be wfh?

Hi, any pregnant moms still working from office instead of home during this period? My company does not have plans to allow front line staff to wfh. It has already met the minimum 50% requirement for staff to wfh by sending backoffice staff home instead. My managers and ceo are aware that I'm pregnant and in first trimester but have not made arrangements for me to wfh. I am worried of being exposed to the covid virus as I have not received any vaccination and my colleagues all do not wear masks during work hours on desk. What should I do? #pleasehelp #1stimemom
