Well that's an unfortunate title truncation. For those scratching their heads but not reading the article: Pao is eliminating salary negotiations for new hires. No word on negotiation of raises though.
Why do you think the policy would be any different for raises?
Every mention of the policy in this article states that it applies to the hiring process. The fact that eliminating all salary negotiation would be an even bigger headline leads me to assume the reporter didn't just miss this detail.
