If I were a Github employee happy with my job and current colleagues, I'd prefer the former solution.
Also, on another point, Github believes itself as a very much hacker culture. And if it's a hacker culture, shouldn't they believe in the Hacker manifesto, where they don't discriminate on religion, race, gender, but on their ability to code?
Certainly there are differences between highly motivated technical staff and many other professions, but it's not like most companies go around making rules and processes to make their lives harder.
>We’re in the planning stages of designing a diversity and communication training curriculum for GitHub employees with input from Hubbers and external experts. Topics will include diversity training, effective communication, giving and receiving peer feedback, and conflict resolution.
Communication is incredibly important at any company, but startups often fail to treat it as such, saying "we don't need meetings to get shit done" or "we hire great people so things will just work out".
Some people, through work or life experience, will have no problem giving constructive feedback at appropriate times, and working through differences of opinion. Others will suck at these things. The latter may otherwise be strong contributors - especially if you were hiring for ninja rockstar coding ability and not explicitly for communication skills - so it's worth helping them acquire those skills, both for their own career and for the company.
In particular, some people with conflict-avoiding personalities may have never experienced productive conflict resolution, unless you consider always backing down and feeling increasingly disempowered to be productive.
Now sure, if GitHub HR (or employees) treat this training as a box-ticking exercise, or use it to encourage bland, conflict-free discussion, the culture will nosedive. But I'll give them the benefit of the doubt.
It seems like a lot of programmers, engineers, hackers, etc. have a strong case of Dunning-Kruger in these areas.
