I do agree that if she didn't tell them at the interview then it is not right. My friend had an employee at her work that did the same thing. My friend is the manager at McCash's country store in Perth, where they sell animal feed, along with a range of smallholder supplies. This girl applied for the job, got it, announced she was pregnant, was off sick all the time with morning sickness. Then when she got further on in the pregancy she was back at work, but announced she couldn't lift anything. Now, its a feed store. The job entails putting sacks of feeding into customers cars- she knew at the interview she wouldn't be able to do it, and yet she took the job anyway. She now is on her paid maternity leave!
