Everyone is different. But the standard amount of time post c section is 6-8 weeks. Personally after I had my guts hacked into I didn't want to move for at least 6 weeks, and then trying to get back into the swing of things takes some time too. Most employers should be aware of people having to take 8 weeks post c section, espcially if it's their first one. So I wouldn't worry about it. They can't fire you for having a child. If they do they would be violating the Family Act of 1979.
