great news if this moves forward. while we at it lets ban ghosting applicants and make companies give a direct rejection email with a reason, it can be as simple as "not qualified" or "we found a better candidate, try again next time". waiting for answers that never come is always the worst part.
Passive aggressive behavior around hiring and HR is a big reason I prefer self employment, I ununderstand some of the CYA reasons but I always find it yucky in the extreme.
The policies around blanket ambiguity for rejections is to avoid any kind of messaging that could lead to potential legal retaliation. Frustrating, absolutely, but most employers just aren't willing to flirt with the risk.
