Bloomberg reports that Apple sent a memo to staff on Thursday advising them of the new timetable, which has shifted from early September to October, and now to January 2022.
Apple's plan, once workers are required to return to offices, demands that employees are present at the office Monday, Tuesday, and Thursday, according to Bloomberg. Remote work will be permitted on Wednesday and Friday.
The memo from Deirdre O'Brien, Apple's head of retail and people, urged employees to get vaccinated -- however, vaccination and testing are not currently mandatory.
Due to changing conditions, Apple currently plans to inform staff one month before it will require them to return to the office.
But the social networking giant has required staff coming to work at its US offices to be vaccinated, and ordered all employees in the office to wear a mask, regardless of their vaccination status.
"Given the recent health data showing rising Covid cases based on the Delta variant, our teams in the US will not be required to go back to the office until January 2022," a Facebook spokesperson said.
