I have worked part time for a retail company for almost three years. I have just been hired in as a full time associate. Under my company's policy, I am not eligible for FMLA untill I've worked 1,250 hours in the last 12 months. I am currently at 760 hours. I plan on telling them I am pregnant but concerned they will fire me. Are they able to fire me since I did know I was pregnant when I accepted the job or am I protected by the Pregnancy Discrimination Act?
