But it sucks breaking up too, but I don't see too many people lobbying to pass laws requiring girlfriends to give thirty days notice before dumping their asses.
You're right, but then again, your job is ostensibly what you do in order to make money in order to have a place to live and food to eat. Possibly for your family, too. If I split with my girlfriend, I don't have to find another in a very short period of time in order to continue eating, having a home, et cetera.
(Yes, I know this ignores the case of someone living with his girlfriend and depending on her to support him. I'm not sure what you can do about this kind of scenario, but it is VERY different from a hardworking person suddenly fired from his job with a wife, children, and possibly elderly parents to support.)
