Honestly, this isn't something I expected from a Microsoft company. I thought they were much better about this than other tech companies?
I worked there in the UK for ten years and it's an incredibly diverse company which places huge importance on diversity and inclusion, including explicit training on the topic. I worked with colleagues from across the lgbt spectrum, of all sorts of races and religions from around the world (I had a project with a fully remote team covering 6 countries), physically disabled people, and as I left, MS were proactively recruiting non neurotypical people. It was great. So, organisationally, they are awesome.
Which is why this is even more awful to read. It's just so unexpected. I'm shocked and appalled at what was said to this poor person, it's just disgracefu, and sounds like an absolute failing in that management chain.
I imagine there will be repercussions from the ms org now this is more widely known.
