Being a PWS in the Workplace and How to Self-Advocate

Being a PWS in the Workplace and How to Self-Advocate Long time lurker, first time poster. This is piggybacking on the post asking the community if their stutter was used against them in a professional setting, aka work. Want to get a gauge on the "average" treatment PWS received in while at work, and whether the experiences of other PWS are similar, or, I hope, vastly different to my own. I don't know how much of what I perceive is happening is me being a weak self advocate and/or letting the benign things people do get to me or people being cruel on purpose, so maybe I can get some help on that front, too. At a job which I interviewed pretty fluently for and got, I was told by a coworker that the manager told her I wouldn't have gotten hired if they knew I was a person who stuttered. A former supervisors have told me they had to argue with the manager to hire me because I blocked on my name during the interview. Managers have told me in person that all I had to do is apply for a job and it's a good as mine, but when called for an interview, told that the "position was full" after I block a couple of times. One guy even laughed into the phone and hung up on me during a tough block. That's not all, folks! At my current position, I'm a technical writer, I've been ignored when speaking, been spoken over, have had coworker's "warn" people that I'm a PWS and express pity about my stutter within earshot, and have people switch projects or tasks around so I have minimal, if any, speaking roles without asking or telling me. Now, how much of this is people being thoughtless jerks or people practicing benevolent ableism, I don't know. Part of this is my fault; historically I've been a weak self-advocate when it comes to my speech impediment. The few times I have self-advocated in my current position, I've left the conversation feeling that I did something bad even by bringing it up. Are my experiences similar to anyone else? How do do self advocate for yourself in the workplace? Do you even have to advocate for yourself?
