I know for a fact that Duke supports it. I've got a friend who has worked remotely since the pandemic, and her department has said that they don't see any changes in remote status for the distant future. She and her group are still as productive, and the silver lining is she's saving tons on gas. In reality, it's almost like having a raise since she doesn't have her 30 minute commute twice a day.
Q "Why do you like Duke, you didn't even go there." A "Because my art school didn't have a basketball team."
