AT&T CEO John Stankey, in a note to employees accessed by Business Insider, asked them to either work from office for five days/week or quit. Referring to people who opposed the work-from-office directive, Stankey quoted ex-US Army General Eric Shinseki, saying, "If you dislike change, you're going to dislike irrelevance even more." "Commit to adjusting your own behaviours," he added.
