The ability to speak English clearly should be an important factor in considering the employment of teachers and professors (in the United States). CMV.

Note: Although I do hold this opinion, it feels prejudiced to me so I am genuinely interested in having my V C'd.

I think this opinion is particularly applicable to undergraduate institutions, so I will focus on them. If a university offers an education to undergraduate, it should be concerned with its ability to provide a strong education. Most critical to this aim, is the hiring of professors that are good at teaching. 

Being good at teaching can be roughly defined as the ability to help students understand a subject. Many schools go to great lengths to judge the teaching ability of their professors, conducting surveys, eliciting student recommendations, etc. However, I have never seen a question like "were you able to understand the professor's speech during lectures?" 

I have some professors that speak in such a thick accent that I have to strain to make out their words. This has a huge impact on my ability to learn (and therefore the professors ability to teach). Therefore, if a university does claim to value teaching ability in its employees, it should consider the speaking ability of its employees.

Just because you have never seen a teaching survey that questions comprehension doesn't mean it's not being considered. The administration is well aware of what each professor sounds like - they did interviews, and they sit in meetings and such. They are not ignorant of the handicap of an accent, and have taken that into consideration at the time of hiring the professor.

Also, there is not a limitless supply of experts worthy of being professors. Get rid of all the professors with accents, and who will you replace them with?
