Microsoft has been "continually monitoring conditions" in its US-based offices, DelBene wrote, which has influenced the decision to move the earliest possible date back form July 6, which it had announced last fall.</p><p>Local Microsoft leadership will be able to make individual decisions on whether their office opening dates need to be pushed back past September 7 based on conditions in their own regions, the email said, and employees may also speak with their managers if they wish to have different work arrangements even after Stage 6 is reached. While workers will need to seek that approval, Microsoft has previously said that <a href="https://www.businessinsider.com/microsoft-employess-to-work-from-home-permanently-2020-10">permanent remote work</a> was an option.</p><p>Other tech firms have been slowly rolling out their reopening plans as well. Facebook, Twitter, VMware, Atlassian, Salesforce and others have all <a href="https://www.businessinsider.com/salesforce-employees-can-work-from-home-permanently-2021-2">rolled out the option for employees to work from home permanently</a> even after offices become safe.</p><p>Other firms, however, plan to make permanent remote work the exception and not the rule. </p><p>Amazon plans to return to an "<a href="https://www.businessinsider.com/amazon-employees-upset-office-centric-culture-plans-2021-3">office-centric culture"</a> where most people start going back to offices by early fallabout 10% of its corporate employees have already started going back. Similarly, Google plans to start <a href="https://www.businessinsider.com/google-return-to-office-plan-us-employees-april-2021-3">reopening its offices,</a> though working in them will be voluntary for US employees until September. From there, employees can apply to work remote for up to 12 months, but only if they can prove exceptional circumstances.</p><p>Google in its recent note to employees also encouraged them to get vaccinated, though did not say it was a prerequisite to returning to offices. Microsoft's email did not mention vaccinations. </p><p>Insider has reached out to Microsoft for comment.</p><p><a href="https://www.businessinsider.com/microsoft-office-reopening-september-coronavirus-summer-plans-2021-4#comments">Join the conversation about this story »</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/pikes-peak-hill-climb-colorado-most-dangerous-racetrack-2020-2">Why Pikes Peak is the most dangerous racetrack in America</a></p> Click here to read full news..
