Hello, I am a total newbie when it comes to pregnancy and all the legal stuff. At the moment I am working a very physically heavy and hard job, I have to lift heavy stuff like big microwaves and big TVs. When should I tell my employer that I am pregnant? I am almost 6 weeks now. And when can you leave work for maternity leave? When is the earliest date that you can take it? Also, if I am an agency worker, can they end my job just because I am pregnant? What should I do? Please help. This is my first time being pregnant and I am originally not from UK, so I dont know how it works here.
