Just because the word “work” is in there doesn’t mean it is prohibited.
You know, farmers still have to milk cows on Sunday, harvest crops on Sunday.
Doctors may have to operate on Sunday and they certainly have to care for patients on Sundays.
Public transportation runs on Sundays.
Firefighters have to fight fires on Sundays.
There is necessary work --even ‘servile work’–that must be done on Sundays. And there are plenty of trivial things that aren’t called work but involve the use of mental and physical work that get done on Sundays without a second thought.
The choir at your church sings --and often practices right before Mass–on Sunday.
You have probably gone to a dance or a sports event on a Sunday.
You might even wake up on a Sunday and go out for a 2 mile walk or a 5 mile run, or just do some crunches at the gym.
You might sit down with your sewing, your woodworking, any hobby; you might cook, bake, paint, create, read War and Peace . . .
For the vast majority (99%) of us, provided we are not out there deliberately doing unnecessary busy work of ANY kind in preference to resting and giving attention to God and those who need us, we’re good.
That means that the workaholic who decides that he just ‘has to’ spend Sunday doing anything but being home with his family, whether he’s at the office, the gym, or appearing to be ‘relaxing’ but who is neglecting his family and his God (or hers, women can do this too) is 'breaking the Sabbath",
but the farmer who is up at 3 a.m. and working the whole Sunday, but making sure to take even a few minutes to bless the Lord, hug and thank his wife for all her help, demonstrate family committment to the kids, etc., is NOT breaking the Sabbath.
I know I’ve said it before, but gosh, is common sense completely dead in modern society? And this is NOT a snark at the OP. It’s a perfectly good question that he asked because, apparently, the answer just hasn’t been communicated well, partly because society has become so secularized, so fixated on loopholes, and so poorly educated regarding not so much rules (though they’ve been jettisoned a lot) but on why it is love of us for God, and love of God for us, that makes the Sunday rest so important for our spiritual life.
