I get that, and have had the same from both the ship side and within Ottawa, but that's really nothing to do with the merits of hybrid work vice working in the office (and there are still plenty of people on the coasts doing hybrid work, which makes sense for the jobs). The same people that aren't answering emails now weren't doing it before, and "Ottawa" is spread out over probably hundreds of organizations spread out across the NCR (with detachments across the country).
I'm personnally way more productive WFH at some pretty significant aspects of my job that take up a lot of time, especially wearing 3 or 4 hats (down from I think 7 a few years ago). There is a huge amount of paperwork to churn through, so cranking on tunes and not getting interruptions lets me do that. When I go into work I can't do that, so that's when we do the whiteboarding/talking through issues etc, and it generally works out okay.
If they want to order us back in just because, that's fine, but I'm not putting in extra hours to cover off the chronically underfunded/overtasked stuff they want me to do, and will be putting in a normal 40 and calling it a day. If they can't trust me to manage my subordinates working arrangements within the DND hybrid guidelines, I guess I can't be that important anyway.
Sure, it's a benefit, and yeah, I get that folks on front line units won't have any sympathy, but frankly we have the infrastructure and processes in place to allow hybrid work, so the jobs that can adapt to it really should, and it's a free way to not hurt retention further. Especially when you stick people in a frustrating mess where there are dozens of approval gates to get the basics done, then you do stuff like turn off NICP taps so we can't buy parts.
Lots of folks have options to do something else for the same/more money etc, so someone more open to something like WFH is just another nice way to boost poaching from DND. Ironically pretty sure I could walk out and consult back for the next 10 years for a very major project RCN will be required by legislation to get done, which I'd be happy to do in uniform if they would just left me alone to do it.
