One of Amazon’s (AMZN.O) top executives defended the new, controversial 5-day-per-week in-office policy on Thursday, saying those who do not support it can leave for another company.

Speaking at an all-hands meeting for AWS, unit CEO Matt Garman said nine out of 10 workers he has spoken with support the new policy, which takes effect in January, according to a transcript reviewed by Reuters.

Those who do not wish to work for Amazon in-office five days per week can quit, he suggested.
