My guess is the nail is officially in the coffin given the description of the new MBA position:
Leads essential activities that drive AYS and all other business processes. Focus on recruitment and onboarding activities for new colleagues, OPTIMIZE WEEKLY STORE SCHEDULES and manage execution of all store admin functions such as budget and cash office functions
Also:
Is the AST department going away completely or is just under a new name? Or just the people leader under a new name? Are AST associates expected to ring at AYS now?
