That's a pretty big blanket statement. I think most people would agree that people that stutter often have it worse when they're nervous or under pressure. Not always, but anxiousness usually makes it worse for most. I'm not saying it's impossible to have that job, I'm just saying that it may not be the best fit for the average stutterer. God knows stuttering hinders a lot of people even in day to day activities. I mean, one of the most common fears of a stutterer is phone calls. Though of course every stutterer is different and you probably know what can or can't do. But some jobs require a response in seconds or as fast as possible. And if you block for a while, well that may be a problem in that kind of job. Maybe it's just me, but as a stutterer I just don't believe that someone with a stutter can do every single job as well as someone that doesn't. And that's fine. That applies to a lot of other things to, like people with anxiety, dyslexia, etc.
