Microsoft Corp., one of the first American companies to ask staff to shift to remote work over a year ago as the coronavirus pandemic hit, is ready to initiate welcoming employees back to the office.Microsoft’s Redmond, Wash., headquarters and nearby campuses will initiate shifting to a hybrid-work approach on March 29, with some employees returning to office desks while others work from home. The software company’s office locations spanning 21 countries will be ready to accommodate additional workers in compliance with guidance from local authorities. The first guidance affects an estimated 20% of Microsoft’s more than 160,000 employees. Microsoft stated that it doesn’t expect to recall all employees soon. Once the pandemic is no longer a significant threat to communities, Microsoft stated, the company expects a partial work-from-home schedule to be routine for multiple of its jobs.
