This guy s 100% accurate. When I was a contractor for the NWS in the mid 2010s they were working aggressively to get their HQ staff setup to telework at least some of the time to save on office leases. They built out a large fix work space in their silver spring building and when it went live they were able to vacate an entire floor, saving something like a million dollars in month in lease, utilities, etc costs.
This mindset of return to office to force attrition also seems less likely to work for federal employees that often need to work in the office at least part time anyways, and often have very strong union protections that will cost a ton for the government to fight through.
On top of that, the costs to return employees to offices will be astronomical both in fitting out those office spaces again and in terms of supporting infrastructure like transit costs. A lot of those additional costs get borne by state governments and often passed on to the federal government through grants and chargebacks for various services.
Another plus one for Proton with your own domain.
Self hosting sounds good, but it’s fraught with mines that if you don’t know what you’re doing can take from “can’t send email because my domains been back listed” to “everything in my network is now sending spam to the entire world”. Sure, many folks self hosting sounds with no issues, but the price for configuring something wrong can be steep and IMO is just not worth the trouble and risks when there are good options for encrypted, privacy protecting email services for a reasonable price.
