Newer leadership is decimating the existing organizational structure to purge the organization of "legacy people" for better/worse so they can install their own direct reports.
Some practices, not unfamiliar to most experienced people, are unethical and borderline illegal. Leadership will retroactively tank reviews for high-performing individuals, citing personal opinions and erroneous data to justify reductions in force (and prevent future lawsuits).
As existing employees watch their colleagues disappear weekly, they have zero psychological safety or motivation to continue performing well. Something that's eroding morale is seeing job postings for non-US locations with titles that match existing roles.
