Taxi company Uber will also require employees in the United States to be vaccinated before they are allowed to return to the office, following significant tech companies Google and Facebook.
Uber also postpones the return to the office worldwide until the end of October.
Uber is doing this because of the highly contagious Delta variant of the coronavirus. The majority of infections in the United States are now due to the Delta variant.
In April, Uber thought that staff would be able to return to the office in mid-September.
