For me, email is really the way I hear about things. I have a smartphone, iPad, and multiple machines. On one of those, I'll get a note. It could be a phone call, but that's rare.

From there I might call or forward the notice to someone else, or possibly connect with VPN. I might even call and be remote hands for someone if that's quicker.

Getting work when you aren't at work is a reality, but it doesn't have to mean you work 40+ hours and then respond to things. I would definitely set boundaries and push back to get time back, and better balance in your life.
