An employer should have the right to choose whether he hires a pregnant woman or not. He needs an employee that will be there to work. If he hires her, when she has the child, he is then forced to keep that position open for her for a period of time. If he doesn't have that employee to do that work, who is going to do it? You? He than has to hire temporary help and train them, after training this new employee who left after a few months to have a child. Then when she comes back he has to spend time to retrain her. This is not a viable option and very costly for many businesses.
