I actually just keep my VPN running all-week long since I'm too lazy to authenticate every morning.

For me, work ends when I switch my monitor inputs to my personal computer.

That only works if you don't have the chat/emails on your phone and if you can just switch that off. There are enough companies that allow business phones for personal use (can be great to save costs) which means you always have your business phone with you. And on the phone no one sees if you're working before they call you.
