If it's "work work" (tasks you're being employed to do) then it's illegal in most of the EU to work every day — see the Working Time Directive¹, which requires at least 24 hours of non-work time every week, for most occupations.
I'm paid to work on free software. In the last year, my Github profile shows a single commit on a weekend, when I made a pull request on a browser extension I use. I'd rather spend my weekend time away from computers :)
