This sounds incredibly familiar.
I worked for DoD for almost 10 years, and am potentially moving back onto another project there if we win a recent bid. As it stands, I work with another organization that had steadfastly refused to do any of its administrative business on the unclass side. Never really understood that, but COVID turned that all on its head and our team was the first in that organization to prove that it was possible to continue working at nearly full capacity when we were asked to telework. Now that we have the infrastructure set up, we're more productive than ever before, and there's a push to move a lot of what we do on a regular basis onto the unclass side. Of course, now the organization is pushing to bring people back into the office, but luckily our client understands that our team is killing it while working remotely so they're in no rush to try to bring us back.
Like others, I don't mind going into the office, but our developers have been 100% telework for a year and have absolutely no need to be in the office. As a PM, it makes sense to go in, but there's really no need to be in the office every day anymore. Give me a desk I can hotel at a couple/few days a week and let me telework the rest of the time. Much better work/life balance and is a sweetener for any potential candidates to work for your organization. We definitely see this in tech - you need to do everything you can to get the best candidates - and allowing work from home is a huge factor in enticing them to work for you.
