Something important we need to understand is that most people are ignorant about stutters - or really any speech impediment for that matter. Because stutters are uncommon, most people never come across a situation where they have to learn what it really is. Situations like yours are great opportunities to teach people. When that person said to work on your talking skills, they basically just admitted they don't know what a stutter really is. I can't really blame them tbh, they probably just never had to learn what one was, and thought you were just different or weird. Of course, this is assuming they were referring to you which we don't know for sure. But if they were, that's probably why they said that. They just don't know. A great thing to do (not in a hostile, confrontational way), is to tell the people you work with about your stutter, and briefly explain how it works. Not only are people intrigued by differences, but they will at least be given some standard knowledge about a stutter and would feel stupid to say something like that again. If you tell that person that there is no cure for most stutters, I can't imagine they'd make that ignorant comment again. I'm not suggesting you sit your coworkers down and have a deep conversation about it - then they will hate you lol. But just to briefly mention it at some point, will dilute a lot of the annoying comments. Of course there are still people who are just straight up mean, but decent people will make the conscious choice to not insult you once they understand the basics, which is a good thing. I hope you don't let this situation discourage you from speaking! One person doesn't deserve to mute us - we need to speak *more,* not less.
