From the post: " Dell's "return to office" mandate has left employees confused about which offices they can use and the future of their jobs – and concerned the initiative is a stealth layoff program that will disproportionately harm women at the IT giant.
As El Reg broke this month, Dell told employees they each needed to choose between resuming a hybrid work schedule – working from a corporate office part of the time – or continue working remotely. Those who chose to remain as remote workers were effectively making a career-limiting decision."
