No, it's not safe to say. You can have good oral communication skills AND have a stutter. I'm saying "good" instead of "excellent," because that's a bunch of crap when they say "excellent this and excellent that." Very few people are "excellent" at anything. If they hire someone decent in most ways, they are doing well. You know....this comes down to how you feel about yourself at the moment, because, with most employers, that's what's gonna make the difference. If you are able to convey that, yeah, you have a stutter, but it does not interfere with your work (even if that's a bit of an exaggeration), they will take their cue from that. MOST of them. And if they don't, if they think someone with a stutter cannot do the job no matter what? You don't wanna work for that person. Please don't skip applying to jobs with that tired phrase in their description? Wishing you the best.
