Many white-collar workers are lucky enough to have creative-class jobs that are satisfying, which is great as long as you're still able to carve out true, work-free leisure at some point. But there's been a kind of sneaky reframing of work as play as the Silicon Valley model has been imported into other fields. Now you see adult offices that look like nursery schools, and staff paintball parties, work cultures that encourage the "We're a family here!" fantasy while preventing workers from going home at a reasonable hour to be with their actual families.

On a societal level, what happens to community when people don't have time to gather or connect, in person, not just over social media? Not having time off becomes a public-interest issue. It means the erosion of social bonds, less civic contribution and participation. Loneliness is on the rise in North America; we find ourselves too busy for true connection, prioritizing work over life.

Sunday blues often hit because the weekend was only about shopping and chores. If you can clear up some of that domestic detritus on weeknights, you might reclaim some time for what matters. Maybe the laundry can wait until Monday.

It used to be that wealthy people were the leisure class, and having time off was a status symbol. That's switched now: being busy and overworked is the reality for many white-collar workers, and there's a kind of perverse currency to that, competitive busy-ness. At the other end of the income scale, there's a swath of lower-wage workers who are underemployed or unemployed, with too much unwanted leisure, and zero status for that. For shift workers, devices mean they're accessible in ways they weren't before, susceptible to that call from the boss to log more hours.

When we don't get that escape from our work selves, I think we feel its absence on a deep, almost primal level. Leisure is uncommodified, unoccupied time where we get to be truly free, so feeling bad about missing the weekend isn't just, "Damn, I didn't make it to the mall!" It's a profound loss.

If you're in the mood for a blushing art house romance, you'll fall for it, too.

On the business side, innovative leaders are beginning to wake up to the fact that this non-stop work trend is bad for business: Google Ireland tested a program called Dublin Goes Dark, where employees turned over their phones at the end of each work day. It seems like a sea change is ahead.
