6 weeks ago I started a new dream job (that has been nearly a year in the planning and that involved relocating my family to the other side of the country for). In the meantime I've had a Mammogram and have been told it's very likely I'm facing a Breast Cancer diagnosis. I'm worried about my new job and how they will see things. I have a 6 month probation period - could they chose to just get rid of me?
