In a statement emailed on Thursday to its employees, Amazon announced that they expect all office workers to return to working in person at least 3 days a week starting September 7th. This new statement comes in more relaxed than their previous stance of returning to an “office-centric culture.” Some exceptions will be made through an approval process.
