New York CNN Business  — 

As states across the country begin to reopen, a growing number of big tech companies are telling employees they can continue to work from home until the fall or even through the end of the year.

Facebook (FB) confirmed to CNN Business on Friday that any employee who can do their work from home may continue to do so until year end. The social network will not reopen most of its offices until July 6, at the earliest.

The move, which was first reported by CNBC, marks a significant extension from its previous plan, which allowed for remote working through at least May. (Facebook previously canceled all in-person events through June of next year.)

Most Google (GOOG) employees will likely continue to work remotely through the rest of this year, CEO Sundar Pichai said at a company-wide meeting on Thursday, according to tech news site The Information. A Google (GOOG) spokesperson confirmed the accuracy of the report. Previously, Google (GOOG) said employees would be working from home until at least June 1.

Online real estate company Zillow (Z) also said employees can work from home until the end of the year. “My personal opinions about WFH [work from home] have been turned upside down over the past 2 months. I expect this will have a lasting influence on the future of work … and home,” tweeted Zillow (Z) CEO and cofounder Rich Barton.

The long-term telecommuting option stands out in an industry known for spending heavily on corporate campuses filled with free food, office slides and other perks. But tech companies including Facebook and Google were also among the first in the US to tell employees to work from home as the coronavirus spread on the West Coast.

While the exact timetables for remote work may vary, each of these tech companies are telling employees the option will remain on the table for months to come.

Amazon (AMZN) said employees who can work “effectively” from home can do so until at least October 2.

“We are working hard and investing significant funds to keep those who choose to come to the office safe through physical distancing, deep cleaning, temperature checks, and the availability of face coverings and hand sanitizer,” an Amazon spokesperson told CNN Business.

Microsoft is also reportedly allowing employees to be remote until October. The company did not immediately respond to a request for comment.
