It varies. When I was a state employee I only took work home when absolutely necessary - prep for a hearing coming up, finishing an order needing to be issued by a statutory deadline, etc. Otherwise I was out the door at 4:30 and wouldn't do work until 8 am the next workday.
Now that I'm with a firm, I still try to leave work at the office as much as possible but since my pay is at least partially linked to my billable hours, I end up doing some work at home just to make sure I stay close to hitting the target for the month/quarter. My firm is good to the extent it's not BigLaw hours requirements, but it's still always in the back of your head trying to hit 6 billable hours each workday, or more if you need to make some up. And some clients are asses and make unreasonable deadlines that can only be met by working ridiculous hours.
So I will be doing some work from my parents this weekend since I've slacked off during the week. Not a ton, but more than I'd do if I was still a state employee with paid vacation (which would be none). And it's my own fault, had I done more work yesterday and today, I wouldn't have to do more this weekend.
