I've worked in 4 retail stores, my job which i have been working now, is depends too much talking on phone and face to face. Because we are selling technical products and you have to explain specs to customers. People get use to your speech very fast and doesn't care if you can help them. If you are good at your job no one cares about your stutter. Just be confident about yourself and your knowledge about the job. I'm 32, and i am working actively since high school. I have eco degree, i didn't even stop working while i were at college. Actually working on a job which forcing you to socialize is helping a lot. I still stutter but very less if i compare to high school years. Btw of course it depends to job qualifications, i believe you are not applying to newscaster job 😁 %95 of jobs it's really doesn't matter how you say, what you say is way more important. Never forget that🤘
