I saw Apple's layoffs in one mu of three

The change of leadership in Apple's HR department, I wonder if this is a precursor to layoffs?
News shows that Tim Cook has appointed a new HR director to replace Deidre, who was previously responsible for both retail and human resources, and a new director from a central US medical technology company
By the way, is this going to be about preparing to lay off employees or maybe perfreview to find people temporarily from outside companies to back the pot?
