If your husband works for a large corporation, you might want to escalate this to the country or state level management. They would take workplace bullying at their regional offices very seriously. Further, this amounts to harassment, you might want to contact a disabilities lawyer. As someone suggested, document EVERYTHING. Please ask him, if someone so much so sniggers or passes a remark, ask him to make a note of it. The date, the time, what was said and how it was handled by the management. At a suitable time in the future, you'd want to present these facts to the upper management about how systemic bullying is taking place at the workplace. As someone who has taken bullying in his stride and at times even extricated myself from situations, I know it can be tough. But there is nothing I regret more today and I really wish I would have stood up for myself. Backing down would be akin to admitting that your husband has lost the battle. Further, as your husband is someone who has recently started stuttering, I can empathise how hard it must be for him to have led a fluent life and then suddenly be thrust into this. Has he sought out speech therapy? And therapy? I am curious to know what brought on the adult onset of stuttering. Has he always been a mild stutterer who suffered a psychological or medical set back recently? Please feel free to reach out to us if there's anything we can help with! Thank you for supporting your husband, now it's time to help him walk!
