Amazon is tightening its rules for disabled employees who want to work from home, as the company pushes for a full return to the office five days a week starting in January. Now, employees with disabilities face tougher steps to get approval for remote work. They must go through a detailed review process, which will also include having their requests signed off by multiple managers. In some cases, they may even have to come to the office for a month to see if personal accommodation works for them.

As Bloomberg reports, the new policy has upset many workers, who feel it adds unnecessary hurdles, especially since some have been successfully working from home for years. Amazon says the changes are part of its broader goal of getting people back into the office and strengthening company culture. CEO Andy Jassy believes working in person helps teams collaborate better and avoid the bureaucracy that has grown during the pandemic.

“We understand this is going to be a change and we’re working with our employees to make it as smooth as possible,” Amazon spokeswoman Margaret Callahan said in a statement. “We continue to believe that the benefits of being together in the office are significant. When personal accommodations are needed, we will provide them, and in some cases, provide flexibility to work from the office. He declined to say how many requests have been approved.

Here’s how it works: Employees with disabilities talk to “accommodation advisors” who review their medical information and previous work setup. Consultants check whether working from home has been effective and whether the office can meet their needs. If they approve remote work, multiple managers must sign off as well.

While Amazon says it is committed to supporting its employees, critics believe the process is too complicated and could force some people to leave their jobs. The company has not shared how many requests have been approved under the strict rules.

Under US law, employers must offer “reasonable accommodations” such as reserved parking or special equipment to employees with disabilities. But remote work isn’t guaranteed, giving Amazon leeway to ask people to come back.

For now, many employees are waiting to see how these new rules will be implemented. As January approaches, some people are worried that the changes will make it harder to balance their health and their job.
