We had good HR and great agile processes established at the company where I work. Long before Covid. There truly is a very limited number of roles in the company that benefit from in-office work, and along with the individuals who prefer in-office work, they were provided with a significantly scaled down (and way cheaper, cozy even) work environment, once the situation allowed. Teams have a short catchup meeting twice a day. A long weekly meeting. And there's a monthly company meeting too. Many individuals group up to work in pairs as a matter of course. Something we're well used to as well. Way plenty comms. All online. No mess, no fuss.
Overall productivity increased substantially. Profitability too. Thanks both to the decreased company expenses, as well as the ease with which we can employ from across the country without having to expand office space nor broad incentive to convince them to move here or commute excessively. And, even a sprinkling of foreign employees, among them ones who decided that they can work from anywhere, and so they moved wherever they felt like moving. Eksdom's load shedding moved the cost needle a tiny little bit in small spurts, because the company happily provided viable battery backup. But for the rest, it was all win.
