KL is not entirely out of the picture. The memo from KL didn’t specify that she was leaving, stepping down, or retiring. She expressed gratitude for everyone’s support and wished for future success. No news articles provide a clear narrative of what happened, and perspectives vary across different sources.
DJ's companywide memo reveals that KL took a step back and spoke to DJ, who was already in retirement, to return and take over the company. This was a strategic move for KL to take a leave of absence and rest for a few months. During this period, KL will shadow DJ in operational work. The length of her leave of absence is unclear.
After DJ restructures the company, laying off 20,000 workers to save $2 billion (20,000 workers making $100,000 each = $2 billion saving), DJ will retire. KL will then return, and a companywide memo will announce that the Board of Directors has reappointed her as CEO.
Moral of the story: They’re all friends.
