Starbucks Corp. plans to enforce a stricter return-to-office policy for corporate employees, requiring three days in the office each week starting in January.  Failure to comply could lead to job termination. The memo underscores a more rigid approach to its hybrid work policy, marking an escalation under new CEO Brian Niccol. Exemptions may be requested for disabilities, while sick leave, vacation, and business travel days are excluded from the requirement. Starbucks' policy shift aligns with recent moves by other major corporations, as businesses increasingly push for in-office work amid lingering post-pandemic flexibility challenges.
