Reading the actual text that's included in the article it seems to say that this is a non-poaching agreement for senior level roles. Specifically it says not to "Cold Call." It specifically excludes engineers and non-senior level roles so the allegation that it's over 1M employees is also not accurate as that number would include non-managers.
reading the actual text in the article, how do you come to the conclusion that it is for "senior level roles" only? It talks about "staffing talent" "recruiting teams from any company" "one of our sales guys" Nothing in the article seems to limit it to just senior level roles. Where does it specifically exclude engineers and non-senior level?
