politically correct or grammatically correct?

"Everyone in this class must bring his notebook and safety glasses to each lab."

Now, does that mean the class is made up of all boys? Not necessarily. It used to mean that each person, whether a boy or girl, should bring a notebook and glasses. However, with the growing need to be politically correct, that sentence needs some work.
It could get pretty tedious replacing every his with his/her and him with him/her. Is it really necessary? I'm not saying I'm anti-feminist or anything. It's great that the issue is being raised. But should we really change how the grammar of the English language (and other languages as well, like Spanish) is structured? I think there might be other ways to place women on the same level as men.
