Can’t fully relate, as I changed my name when I changed shifts and departments. The result being neither my manager nor any of my coworkers has ever known me by my deadname. So that particular bit of awkwardness was avoided.
But without a doubt, changing my name at work was one of the best decisions I ever made. Still need to update my badge, but everyone uses my preferred name and compliments me on it. Feels so amazing to constantly hear it, beginning to heal a lifetime of hearing a name I loathed.
