One of my friends who is an awesome salesman and was recommended by the person hiring for the job was not hired for the position by HR because he doesn't have his GED. The guy is super smart and doesn't have his GED because of some unfortunate circumstances regarding his classes being on the 2nd floor of the school and having broken both legs.
Now he's going and finishing up his GED in a couple weeks and will continue the search.
You do not really believe this do you?
I am very sorry for your friend. Rigid interpretation of the rules can lead to some terrible decisions. However I do not think that requiring a GED increases the likelihood that the employee is going to be the cause of a lawsuit. Humans nature is an odd beast and the list of lawsuit inducing character flaws goes on for miles. If people were able to easily screen for these character flaws during the recruiting process elections would be so much easier...
His school is exempt from the Americans with Disabilities Act?
Maybe they think stalking prospective employees via facebook helps them somehow there...
