Hi there, I need done advice regarding a health and safety issue at work. I am 16weeks pregnant and am due to return to work tomorrow after my Christmas break. I was just informed by a colleague that our toilet has become blocked and is consistently overflowing, pumping out raw sewage into our bathroom which is beside our workspace. Due to people being on holidays the problem cannot be fixed until Monday, leaving us with no running water or toilet facilities. I am worried about being around an unsanitary area and the harm this may cause my baby and my health. Can you advise on whether I am over reacting or have cause for concern? Many thanks , Ellen
