Every so often we get a news story around here, about a woman getting knocked up and taking her maternity leave. Somehow they always manage to get a promotion to some manager/better paid position before going on leave. Then the company has to find a replacement and is "obligated" to give her position back when she returns...

The story is usually the background for a lawsuit, where the woman contests her firing. and the company saying that she knew she was pregnant and deliberately took the position when she knew she would not be able to do the work.
